I am trying out Gatling first time.
But when I try to add .inferHtmlResources() i got following error:
value inferHtmlResources is not a member of com.excilys.ebi.gatling.http.config.HttpProtocolConfigurationBuilder
The same mattes when I get to execute part for resources:
value resources is not a member of com.excilys.ebi.gatling.http.request.builder.PostHttpRequestBuilder
Pseodo part of what I am doing
Part 1:
val httpConf = httpConfig.baseURL(urlBase).inferHtmlResources()
Part 2:
.exec(
http("Login")
.post(loginUrl+"/security/signin")
.headers(actionPostHeaders)
.param("""username""", """${loginName}""")
.param("""key""", """${key}""")
.check(status.is(200))
.check(headerRegex("Location", """.*/loggedIn"""))
.resources(http("request_5")
.get(tipUrl + "/authentication/authenticated")
)
).exitHereIfFailed
...
setUp(scn.users(numUsers).ramp(rampUp(numUsers)).protocolConfig(httpConf))
I am not used to Scala. But can it be the version of gatling?
Gatling HTTP protocol settings are created using http method, fe.: http.baseURL("http://localhost").inferHtmlResources(). Moreover I see that you are using some com.excilys.ebi.gatling classes, I think that those are extremely old packages from times when Gatling was just an internal project. Please make sure you are using newest version of gatling from io.gatling package.

now I'm trying to conduct load test with gatling.
I have been trying create gatling's simulation script via gatling recorder and
it was going well.
but, when I executed that, I encountered file not found error below although there are files
(in this case /step1/0006_request.json is exist)
request_6: Failed to build request: Resource /step1/0006_request.json not found
there are many json files and that error occurred some of specific post requests.
every requests which is failed are composed following setting.
using request header 'headers_6' below
using RawFileBody method
(even if this is obvious thing because content-type is 'application/json')
I already have been using 12 hour over and I have to finish my task in a timely manner.
I'm so sorry about that I can't share my application which is target of this issue.
if anyone have any idea or kindly want to more detail please ask me.
val headers_6 = Map(
"Content-Type" -> "application/json",
"Origin" -> "applicationServerURL")
.exec(http("request_6")
.post("requestUrl")
.headers(headers_6)
.body(RawFileBody("/step1/0006_request.json"))
.resources(http("request_7")
additionally, I checked json files which were created by gatling recorder on 'resource' directory, them contains only one char 'X'.
this means Gatling recorder doesn't capture request json file's content?
env:
Gatling version gatling 3.5.1
Used Browser: FireFox
I just solved this issue.
this issue was caused by very simple fact.
firstly, I encountered error message below
request_6: Failed to build request: Resource /step1/0006_request.json not found
and I have to check the file paths although this script was auto created by gatling recorder(do not trust gatling tool).
The auto created file path was absolute path and start with ‘/’. And the script started to work once I remove the ‘/’.
I referred other post on stack overflow, and it was written that file path must be written with absolute path if you are using gatling version 3 or later version.
I hope my reply can be informative to someone who may be having same issue as me.
Using 'relative path'.
//As is
.exec(http("request_6")
.post("requestUrl")
.headers(headers_6)
.body(RawFileBody("/step1/0006_request.json"))
.resources(http("request_7")
//To be
.exec(http("request_6")
.post("requestUrl")
.headers(headers_6)
.body(RawFileBody("step1/0006_request.json"))
.resources(http("request_7")
Compiler error when using example provided in Flink documentation. The Flink documentation provides sample Scala code to set the REST client factory parameters when talking to Elasticsearch, https://ci.apache.org/projects/flink/flink-docs-stable/dev/connectors/elasticsearch.html.
When trying out this code i get a compiler error in IntelliJ which says "Cannot resolve symbol restClientBuilder".
I found the following SO which is EXACTLY my problem except that it is in Java and i am doing this in Scala.
Apache Flink (v1.6.0) authenticate Elasticsearch Sink (v6.4)
I tried copy pasting the solution code provided in the above SO into IntelliJ, the auto-converted code also has compiler errors.
// provide a RestClientFactory for custom configuration on the internally created REST client
// i only show the setMaxRetryTimeoutMillis for illustration purposes, the actual code will use HTTP cutom callback
esSinkBuilder.setRestClientFactory(
restClientBuilder -> {
restClientBuilder.setMaxRetryTimeoutMillis(10)
}
)
Then i tried (auto generated Java to Scala code by IntelliJ)
// provide a RestClientFactory for custom configuration on the internally created REST client// provide a RestClientFactory for custom configuration on the internally created REST client
import org.apache.http.auth.AuthScope
import org.apache.http.auth.UsernamePasswordCredentials
import org.apache.http.client.CredentialsProvider
import org.apache.http.impl.client.BasicCredentialsProvider
import org.apache.http.impl.nio.client.HttpAsyncClientBuilder
import org.elasticsearch.client.RestClientBuilder
// provide a RestClientFactory for custom configuration on the internally created REST client// provide a RestClientFactory for custom configuration on the internally created REST client
esSinkBuilder.setRestClientFactory((restClientBuilder) => {
def foo(restClientBuilder) = restClientBuilder.setHttpClientConfigCallback(new RestClientBuilder.HttpClientConfigCallback() {
override def customizeHttpClient(httpClientBuilder: HttpAsyncClientBuilder): HttpAsyncClientBuilder = { // elasticsearch username and password
val credentialsProvider = new BasicCredentialsProvider
credentialsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials(es_user, es_password))
httpClientBuilder.setDefaultCredentialsProvider(credentialsProvider)
}
})
foo(restClientBuilder)
})
The original code snippet produces the error "cannot resolve RestClientFactory" and then Java to Scala shows several other errors.
So basically i need to find a Scala version of the solution described in Apache Flink (v1.6.0) authenticate Elasticsearch Sink (v6.4)
Update 1: I was able to make some progress with some help from IntelliJ. The following code compiles and runs but there is another problem.
esSinkBuilder.setRestClientFactory(
new RestClientFactory {
override def configureRestClientBuilder(restClientBuilder: RestClientBuilder): Unit = {
restClientBuilder.setHttpClientConfigCallback(new RestClientBuilder.HttpClientConfigCallback() {
override def customizeHttpClient(httpClientBuilder: HttpAsyncClientBuilder): HttpAsyncClientBuilder = {
// elasticsearch username and password
val credentialsProvider = new BasicCredentialsProvider
credentialsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials(es_user, es_password))
httpClientBuilder.setDefaultCredentialsProvider(credentialsProvider)
httpClientBuilder.setSSLContext(trustfulSslContext)
}
})
}
}
The problem is that i am not sure if i should be doing a new of the RestClientFactory object. What happens is that the application connects to the elasticsearch cluster but then discovers that the SSL CERT is not valid, so i had to put the trustfullSslContext (as described here https://gist.github.com/iRevive/4a3c7cb96374da5da80d4538f3da17cb), this got me past the SSL issue but now the ES REST Client does a ping test and the ping fails, it throws an exception and the app shutsdown. I am suspecting that the ping fails because of the SSL error and maybe it is not using the trustfulSslContext i setup as part of new RestClientFactory and this makes me suspect that i should not have done the new, there should be a simple way to update the existing RestclientFactory object and basically this is all happening because of my lack of Scala knowledge.
Happy to report that this is resolved. The code i posted in Update 1 is correct. The ping to ECE was not working for two reasons:
The certificate needs to include the complete chain including the root CA, the intermediate CA and the cert for the ECE. This helped get rid of the whole trustfulSslContext stuff.
The ECE was sitting behind an ha-proxy and the proxy did the mapping for the hostname in the HTTP request to the actual deployment cluster name in ECE. this mapping logic did not take into account that the Java REST High Level client uses the org.apache.httphost class which creates the hostname as hostname:port_number even when the port number is 443. Since it did not find the mapping because of the 443 therefore the ECE returned a 404 error instead of 200 ok (only way to find this was to look at unencrypted packets at the ha-proxy). Once the mapping logic in ha-proxy was fixed, the mapping was found and the pings are now successfull.
I am trying to write a program that enables me to run predefined KSQL operations on Kafka topics in Scala, but I don't want to open the KSQL Cli everytime. Therefore I want to start the KSQL "Server" from within my Scala program. If I understand the KSQL source code right, I have to build and start a KsqlRestApplication:
def restServer = KsqlRestApplication.buildApplication(new
KsqlRestConfig(defaultServerProperties), true, new VersionCheckerAgent
{override def start(ksqlModuleType: KsqlModuleType, properties:
Properties): Unit = ???})
But when I try doing that, I get the following error:
Exception in thread "main" java.lang.NoSuchMethodError: org.apache.kafka.streams.StreamsConfig.getConsumerConfigs(Ljava/lang/String;Ljava/lang/String;)Ljava/util/Map;
at io.confluent.ksql.rest.server.BrokerCompatibilityCheck.create(BrokerCompatibilityCheck.java:62)
at io.confluent.ksql.rest.server.KsqlRestApplication.buildApplication(KsqlRestApplication.java:241)
I looked into the function call in BrokerCompatibilityCheck and in the create function it calls the StreamsConfig.getConsumerConfigs() with 2 Strings as parameters instead of the parameters defined in
https://kafka.apache.org/0102/javadoc/org/apache/kafka/streams/StreamsConfig.html#getConsumerConfigs(StreamThread,%20java.lang.String,%20java.lang.String).
Are my KSQL and Kafka version simply not compatible or am I doing something wrong?
I am using KSQL version 4.1.0-SNAPSHOT and Kafka version 1.0.0.
Yes, NoSuchMethodError typically indicates a version incompatibility between libraries.
The link you posted is to javadoc for kafka 0.10.2. The method hasn't changed in 1.0 but indeed in the upcoming 1.1 it only takes 2 Strings:
https://kafka.apache.org/11/javadoc/org/apache/kafka/streams/StreamsConfig.html#getConsumerConfigs(java.lang.String,%20java.lang.String)
. That suggests the version of KSQL you're using (4.1.0-SNAPSHOT) depends on version 1.1 of kafka streams, which is currently in the release candidate phase and I believe and should be out soon:
https://lists.apache.org/thread.html/780c4458b16590e99261b69d7b41b9ec374a3226d72c8d38885a008a#%3Cusers.kafka.apache.org%3E
As per that email you can find the latest (1.1.0-rc2) artifacts in the apache staging repo:
https://repository.apache.org/content/groups/staging/
I'm still a newbie in Apache Spark dev.
I'm using apache spark to query data from google ads words using spark-google-adwords. But, I always got this org.apache.axis.AxisFault: (404)Not Found
I'm using Scala 2.11 and latest stable Apache Spark. I've tried to look for the solution for this problem, but I still couldn't find out the cause.
Regards,
This issue was resolved by adding a copy of axis2.xml to classpath and overriding few connection manager params as follows:
HttpConnectionManagerParams params = new HttpConnectionManagerParams();
params.setDefaultMaxConnectionsPerHost(20); //SET VALUE BASED ON YOUR REQUIREMENTS/LOAD TESTING etc
MultiThreadedHttpConnectionManager multiThreadedHttpConnectionManager = new MultiThreadedHttpConnectionManager();
multiThreadedHttpConnectionManager.setParams(params);
HttpClient httpClient = new HttpClient(multiThreadedHttpConnectionManager);
ConfigurationContext configurationContext = ConfigurationContextFactory.createConfigurationContextFromFileSystem("**PATH TO COPY OF AXIS2.XML**");
configurationContext.setProperty(HTTPConstants.CACHED_HTTP_CLIENT, httpClient);

I am currently in the process of moving all our Rest tests to the CI server and have noticed that all tests are failing due to the an SSL handshake, now I have successfully disabled this with the TrustManager with our Java test suite, but am unsure how to do it with Scala dispatch library, and havent been able to find many examples that could apply in this scenario.
val JSONstr = "{samplekey:samplevalue}"
val response:String = Http(url("https://www.host.com/path/to/post")
<< (checkInJSONstr, "application/json") as_str)
The following exception is occuring as expected:
javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated at com.sun.net.ssl.internal.ssl.SSLSessionImpl.getPeerCertificates(SSLSessionImpl.java:352)
...
Is there a way to do it cleanly syntactically ignore SSL with the dispatch library?
import dispatch._
val http = new Http with HttpsLeniency
val response:String = http(url("https://www.host.com/path/to/post")
<< (checkInJSONstr, "application/json") as_str)
viktortnk's answer doesn't work anymore with the newest version of Dispatch (0.13.2). For the newest version, you can use the following to create an http client that accepts any certificate:
val myHttp = Http.withConfiguration(config => config.setAcceptAnyCertificate(true))
Then you can use it for GET requests like this:
myHttp(url("https://www.host.com/path").GET OK as.String)
I found this out here: Why does dispatch throw "java.net.ConnectException: General SSLEngine ..." and "unexpected status" exceptions for a particular URL?
