Intermittent connection issues from Springboot to Postgres

Intermittent connection issues from Springboot to Postgres - postgresql

I have a springboot application which connects to a postgres DB.Connection pool used is Hikari.
I have a select query running every 5 minutes.Though it gets executed properly most of the times, i encounter a PSQLException intermittently
org.postgresql.util.PSQLException: An I/O error occurred while sending to the backend.

Below is my hikari properties
hikari:
minimum-idle: 5
maximum-pool-size: 10
idle-timeout: 600000
max-lifetime: 550000
connection-timeout: 600000
Application is hosted in an on premise server connected to an on prem db, also its hosted in AKS connecting to a Azure Postgres DB.
Error is seen in both deployments.
Can someone help me understand why is this happening and suggest a solution.

spark-shell not working on installing apache spark. Error: system cannot find the path specified

I installed Apache Spark, have java and python installed as well. Set up the environment variables as per this article: https://phoenixnap.com/kb/install-spark-on-windows-10
I have also installed winutils.exe.
Initially I was getting an error like :
missing Python executable
defaulting to 'C:\spark\bin..' for SPARK_HOME environment variable.
Please install Python or specify the correct Python executable in PYSPARK_DRIVER_PYTHO
N or PYSPARK_PYTHON environment variable to detect SPARK_HOME safely. To fix this i added a environment variable
Name: PYSPARK_DRIVER_PYTHON
value: C:\Program Files\Python310
Now, on the terminal, C:\spark\bin>spark-shell gives the following output:
The system cannot find the path specified.
The system cannot find the path specified.

How do I fix this?

I think there is issue with your computer name , that contains string and spark libs/scripts not able to understand the same.
spark://DESKTOP-E76IK3L:52769/
can you change your computer/Laptop name to any string(no number, colons in between)
something like : MyDesktop
and try running spark-shell

Filling data from PySpark to PostgreSQL via JDBC does not work

I'm using a JDBC connector for the first time and trying to write a dataframe into a PostgreSQL database. I am strictly doing it according to:
How to use JDBC source to write and read data in (Py)Spark?
Driver is installed and code is specified:
postgres_url = "jdbc:postgresql://<IP_ADRESS>:<PORT>/postgres"
properties = {
"user": "user",
"password": "password",
"driver": "org.postgresql.Driver"
}
df.write.jdbc(url=postgres_url, table="newtable", mode = "overwrite", properties = properties)
After executing the code, I get this error:
py4j.protocol.Py4JJavaError: An error occurred while calling o110.jdbc.

The weird thing is, when I look afterwards into the PostgreSQL, I can see the newly created table, but it is empty. So it seems that installing the connection and creating the structure DOES work, but filling in the data does not. I also tried "ssl" = "false" in the properties, but did not work either. Any suggestions would be greatly appreciated.
Best regards

The connection should be opened between your driver and Postgres AND between your workers and Postgres. Did you check that? The creation of the table is probably done on the driver's side. But then, your workers cannot connect to your DB, therefore, no data. Check that!
You probably have someone in your company who can help you with that. Either, some security/network guy. Otherwise, you need to connect on each driver and test the connectivity to your DB

Running Jhipster in Eclipse Tomcat server

I am trying to run Jhipster in Eclipse Tomcat Server but it seems that it is not working. I have created my gateway in Amazon Linux and checked that it works before bringing it to the Windows Eclipse. As our team is trying to develop in the Windows Eclipse environment, we need to run it in Tomcat.
My error seems to be related to Eureka as shown below. I am wondering if there are a way to fix this error or is it not possible to run it in Eclipse Tomcat in the first place.

When I try again, it may succeed,it's not must.i think it's has nothing to do with timeout time,i set up 6000ms,that's enough

JAX-WS Apache CXF Connection Error

The Apache CXF and the JAX-WS always seems to cause issues. I'm not sure if I'm using it wrongly!
Here is the exception that I get:

Here is what I do to set the context!
private def setRequestContext(proxy: Client, withCredentials: Boolean = false): Unit = {
// set the time out!
val httpConduit = proxy.getConduit.asInstanceOf[HTTPConduit]
val httpClientPolicy = new HTTPClientPolicy()
httpClientPolicy.setConnectionTimeout(mySoapClientConfig.requestTimeout.toSeconds)
httpClientPolicy.setReceiveTimeout(mySoapClientConfig.requestTimeout.toSeconds)
httpConduit.setClient(httpClientPolicy)
if (withCredentials) {
val userCredentials = new UserCredentials
userCredentials.setPassword(mySoapClientConfig.password.orNull)
userCredentials.setUserName(mySoapClientConfig.userName.orNull)
val headerList = Seq(
new Header(
new QName(mySoapClientConfig.targetNamespace, "UserCredentials"),
userCredentials,
new JAXBDataBinding(classOf[UserCredentials])
)
)
import scala.collection.JavaConverters._
proxy.getRequestContext.put(Header.HEADER_LIST, headerList.asJava)
}
}
Could anyone please help me out? I'm able to connect to the WebService using SOAP UI!

I figured out what the problem was. Pay close attention to the following line:
httpClientPolicy.setConnectionTimeout(mySoapClientConfig.requestTimeout.toSeconds)
httpClientPolicy.setReceiveTimeout(mySoapClientConfig.requestTimeout.toSeconds)
The setXXXTimeout takes a long in millis and what I have been passing in was 4 seconds which was understood as 4 millis, which was causing the read time outs!
