[jira] [Commented] (TWILL-172) Getting test failures for "Apache Twill core library" for RHEL 7.2 ppc64le

Terence Yim commented on TWILL-172:
-----------------------------------

Is the failure recurring or transient? If you run the test again, does it still fail at the same test? Also, have you try running it without the {{-Dtwill.zk.server.localhost}} property?

> Hi All,
> I am trying to build and test Incubator Twill for RHEL 7.2 ppc64le. Have installed ibm jdk 1.8 and getting below error:
> Tests run: 3, Failures: 1, Errors: 0, Skipped: 0, Time elapsed: 21.979 sec <<< FAILURE!
> testKafkaClient(org.apache.twill.kafka.client.KafkaTest)  Time elapsed: 5.665 sec  <<< FAILURE!
> java.lang.AssertionError: null
> 	at org.junit.Assert.fail(Assert.java:86)
> 	at org.junit.Assert.assertTrue(Assert.java:41)
> 	at org.junit.Assert.assertTrue(Assert.java:52)
> 	at org.apache.twill.kafka.client.KafkaTest.testKafkaClient(KafkaTest.java:186)
> testKafkaClientReconnect(org.apache.twill.kafka.client.KafkaTest)  Time elapsed: 6.555 sec
> testBrokerChange(org.apache.twill.kafka.client.KafkaTest)  Time elapsed: 6.664 sec
> Results :
> Failed tests: 
>   KafkaTest.testKafkaClient:186 null
> Tests run: 25, Failures: 1, Errors: 0, Skipped: 0
> I have debugged code and following are my analysis:
> For “KafkaTest.testKafkaClient:186 null”, it throws assertion error as “NULL” as thread “KafkaClient” calls “latch.await(5, TimeUnit.SECONDS)” and waits for 5 seconds for background event thread to finish its “execution + signaling after execution” but as "kafkaclient" does not receive signal and as a result it times out after latch of 5seconds and hence assertion error as NULL
> Have tried to execute command:
> export PROFILE="2.7.1"
> mvn test -P $PROFILE -Dsurefire.redirectTestOutputToFile=false -Dtwill.zk.server.localhost=false
> wherein I have installed hadoop 2.7.1 and also have configured for services to start and started all hadoop services. Got same error using IBM jdk 1.8 as well as for openjdk 1.8
> It will be good if you please suggest for the reason for such Test Failure.
> Thanks & Regards,
> Sonali Shrivastava
