------------------------------------------
Hi Terence Yim,
Thanks for the reply. Have you got results installing IBM jdk?
The error below comes in power 64le m/c using IBM jdk 1.8 and open jdk 1.8:
i.e. Failed tests:
KafkaTest.testKafkaClient:186 null
Tests run: 25, Failures: 1, Errors: 0, Skipped: 0
and it fails executing i.e. "latch.await(5, TimeUnit.SECONDS)" .
Analysis done from my side:
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
So it seems this is time out issue which caused above error which is not major.
Thank You.
Thanks & Regards,
Sonali Shrivastava

> 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.
