Getting KafkaProducer: Closing the Kafka producer with timeoutMillis = 9223372036854775807 ms in jmeter log

[ShauryaSid]

Hi , I am new to Kafka but we have a requirement of performance testing for Kafka topic. I created Jmeter script using pepper box Jar file batch - Jmeter3.2_10.2. But we are getting "KafkaProducer: Closing the Kafka producer with timeoutMillis = 9223372036854775807 ms " info in Jmeter log file. and data is not inserting to the required topic. Kindly let me know how can we resolve this issue. Other info: Jmeter 3.2 Kafka 0.10.1.0

• Is kafka version difference ( 10.2 & 10.1) causing issue? Thanks,

Seems to be a connectivity/permissions issue. Can you check with console producer and consumer once and also validate you are able to connect to kafka brokers/zookeeper from JMeter node if running on different machine? If your cluster is kerberized then validate permissions like keytab and jaas file configs.

Hi, As i was running current script from EC2 instance it might be permission issue and it cannot be resolved since they are not agreed to add security group for this machine. But now i tried from my local machine i am getting below error and some null pointer exceptions. 2018-06-11 15:33:41,090 ERROR c.g.p.l.i.PlaintTextLoadGenerator: Please make sure that expressions functions are already defined and parameters are correctly passed. com.gslab.pepper.exception.PepperBoxException: java.lang.NullPointerException at com.gslab.pepper.input.SchemaTranslator.getPlainTextMsgIterator(SchemaTranslator.java:54) ~[pepper-box-1.0%20(2).jar:?] at com.gslab.pepper.input.SchemaProcessor.getPlainTextMessageIterator(SchemaProcessor.java:36) ~[pepper-box-1.0%20(2).jar:?] at com.gslab.pepper.loadgen.impl.PlaintTextLoadGenerator.(PlaintTextLoadGenerator.java:34) [pepper-box-1.0%20(2).jar:?] Kindly let me know the solution and further details if required.

Hi

We are gertting "KafkaProducer: Closing the Kafka producer with timeoutMillis = 9223372036854775807 ms" in jmeter log even running from my local machine. Below are the details:

using SSL protocol from kafka connections ssl.enabled ssl.key.password ssl.keystore.location ssl.keystore.password ssl.truststore.location ssl.truststore.password

Query: Is it required to include Zookeeper details as well since its require kerberos authentication. Suspecting getting this timeout issue due to Zookeeper need. Kindly suggest...

@ShauryaSid As error mentions, please validate functions and variables once again. You can try isolating issue by trying to run sample schema available on Github page. If that schema works then I would suggest to add your functions incrementally to see if you missed anything. If it still fails please provide detailed log here.
