             Summary: Getting test failures for "Apache Twill core library" for RHEL 7.2 ppc64le
                 Key: TWILL-172
                 URL: https://issues.apache.org/jira/browse/TWILL-172
             Project: Apache Twill
          Issue Type: Bug
          Components: core
    Affects Versions: 0.7.0-incubating
         Environment: IBM jdk 1.8,maven 3.3.9
            Reporter: sonali shrivastava
             Fix For: 0.7.0-incubating


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
