NoSuchMethodError: org.apache.spark.sql.kafka010.consumer - scala

I am using Spark Structured Streaming to read messages from multiple topics in kafka.
I am facing below error:
java.lang.NoSuchMethodError: org.apache.spark.sql.kafka010.consumer.InternalKafkaConsumerPool$PoolConfig.setMinEvictableIdleTime(Ljava/time/Duration;)V
Below are my maven dependencies I am using,

Scala Version: 2.13.8
Spark Version: 3.3.0
This my Code snippet to read from Kafka topics:
object consumerMain {
val log : Logger = Logger.getLogger(controller.driver.getClass)
val config: Map[String, String]=Map[String,String](
"kafka.bootstrap.servers" -> bootstrapServer,
"startingOffsets" -> "earliest",
"kafka.security.protocol" -> security_protocol,
"kafka.ssl.truststore.location" -> truststore_location,
"kafka.ssl.truststore.password" -> password,
"kafka.ssl.keystore.location" -> keystore_location,
"kafka.ssl.keystore.password" -> password,
"kafka.ssl.key.password"-> password,
"kafka.ssl.endpoint.identification.algorithm"-> ""
)
def main(args: Array[String]) : Unit ={
log.info("SPARKSESSION CREATED!!!")
val spark = SparkSession.builder()
.appName("kafka-sample-consumer")
.master("local")
.getOrCreate()
log.info("READING MESSAGES FROM KAFKA!!!")
val kafkaMsg = spark
.readStream
.format("Kafka")
.options(config)
.option("kafka.group.id", group_id)
.option("subscribe", "sample_topic_T")
.load()
kafkaMsg.printSchema()
kafkaMsg.writeStream
.format("console")
//.outputMode("append")
.start()
.awaitTermination()
}
}
Below, I am able to see the kafka proeprties I have set in the logs printed on the console:

not recommended to set this option. This option is unsafe to use since multiple concurrent
queries or sources using the same group id will interfere with each other as they are part
of the same consumer group. Restarted queries may also suffer interference from the
previous run having the same group id. The user should have only one query per group id,
and/or set the option 'kafka.session.timeout.ms' to be very small so that the Kafka
consumers from the previous query are marked dead by the Kafka group coordinator before the
restarted query starts running.

I downgraded the version of spark from 3.3.0 to 3.2.2 with the Scala version 2.13.8 remaining the same. For me, it seems the Scala version 2.13 was not compatible with Spark version 3.3.0 . For now I am able to write the Avro data to a file.
And Thanks to #OneCricketeer for your help and support so far!

I hit the same issue with Spark 3.3.0. I did some deep dive and finally found out the root cause: Spark 3.3.0 has built-in dependency on commons-pools v.1.5.4 (commons-pool-1.5.4.jar) while this structure streaming library relies on v2.11.1 which replaced setMinEvictableIdleTimeMillis with setMinEvictableIdleTime. Thus the resolution is to add commons-pool2-2.11.1.jar to your Spark jars folder. This jar can be downloaded from Maven central https://repo1.maven.org/maven2/org/apache/commons/commons-pool2/2.11.1/commons-pool2-2.11.1.jar.
I've documented the details on the page if you want to learn more:

Class [ com.sun.xml.ws.assembler.jaxws.HandlerTubeFactory ] does not implement [ com.sun.xml.internal.ws.assembler.dev.TubeFactory ] interface

I have tried to generate the java code from wsdl2java by using cxf-codegen-plugin .
Code was generated and can see the response in my eclipse test class(tried to call few methods and getting result properly).
But when I created jar of this code and moved to Weblogic server classpath (I have few jsp pages calling this wsdl2java generated code), It calling my methods properly but every time getting Runtime exception.
Note: I have moved all the dependent jars too inside weblogic classpath.
Below is the Exception snapshot:

i haven't run this program to see but it seems you are using kafka 0.10.2 and smallest is deprecated please use earliest instead.
You need add this two commands;
streamingContext.start();//start this app.
streamingContext.awaitTermination();//prevent this app close.
And I see you use http* value for bootstrap.servers. Delete the http prefix.
By the way, if you set spark conf in the code. It's useless set the same value in the command line.
Just check it. If the error exist as before. please let me know.

“value $ is not a member of StringContext” - Missing Scala plugin?

I'm using maven with scala archetype. I'm getting that error:
“value $ is not a member of StringContext”
I already tried to add several things in pom.xml, but nothing worked very well...

I have no idea about how to fix it. Does anybody have any idea?
Add this.. it will work
val spark = SparkSession.builder().getOrCreate()
import spark.implicits._ // << add this
You can use the col function instead just import it like this :
import org.apache.spark.sql.functions.col
And then change the $"column" to col("column")
Hope it helps
#Apurva's answer initially worked for me in that the error vanished from IntelliJ
But then it resulted in "Could not find implicit value for spark" during sbt compile phase
I found a strange work-around by importing spark.implicits._ from SparkSession referenced from DataFrame instead of one obtained by getOrCreate
import df.sparkSession.implicits._
where df is a DataFrame
This could be because my code was placed inside a case class that received an implicit val spark: SparkSession parameter; but I'm not really sure as to why this fix worked for me
I'm using spark 1.6. The above answers are great but unfortunately doesn't work in 1.6
The way I solved it was by using df.col("column-name")
val df = df_mid
.withColumn("dt", date_format(df_mid.col("timestamp"), "yyyy-MM-dd"))
.filter("dt != 'null'")

it is seems scala version uncompatible,but i see the document of spark ,spark 2.10 and scala 2.11.8 is ok.
that is my pom.xml and that is just a test for spark to write to elasticsearch with es-hadoop,i have no idea how to solve this exception. `

Generally NoSuchMethodError implies the caller was compiled with a different version than was found on the classpath at runtime (or you have multiple versions on the CP).
In your case, I'd guess that es-hadoop is built against a different version of Scala I've not used maven in a little while but I think the command you need to get some useful into is mvn depdencyTree. Use the output to see which version of Scala es-hadoop is built with and then configure your project to use the same Scala version.
To get stable/reproducible builds I'd recommend using something like the maven-enforcer-plugin:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-enforcer-plugin</artifactId>
<version>1.4.1</version>
<executions>
<execution>
<id>enforce</id>
<configuration>
<rules>
<dependencyConvergence />
</rules>
</configuration>
<goals>
<goal>enforce</goal>
</goals>
</execution>
</executions>
</plugin>
it can be annoying initially but once you have all your dependencies sorted you shouldn't get issues like this anymore.
use dependency like this
<dependency>
<groupId>org.elasticsearch</groupId>
<artifactId>elasticsearch-spark-20_2.11</artifactId>
<version>5.2.2</version>
</dependency>
for spark 2.0 and scala 2.11

Hi I was facing the same issue myself, I found a solution so the snippet are being created, by changing from
<phase>prepare-package</phase>
to
<phase>generate-resources</phase>
but still facing an issue that snippet are getting created after html is getting generated, which is why it's not included as part of html.
Though I am still looking into that part, for now there is a temporary solution to this, first I execute mvn clean test
then once snippet get generated
again execute mvn test and proper html doc get's generated.
This not a clean solution, and I am still looking for a better solution to this issue, but it's getting the job done for now.
