Terence Yim commented on TWILL-172:
-----------------------------------
Hi Sonali,
The result of the assertion is simply because the unit-test doesn't get the
expected result within 5 seconds, which the root cause can be anything that
causes the expected message not received by the Kafka client (e.g. the Kafka
server or ZooKeeper cannot startup during unit-test run).
I have yet to setup the IBM JDK yet. In the meantime, can you run this command
and attach the output of it?
{{mvn clean test -Dtest=KafkaTest -DfailIfNoTests=false -pl twill-core -am
-Dsurefire.redirectTestOutputToFile=false}}

> Project: Apache Twill
> Issue Type: Bug
> Components: core
> Affects Versions: 0.7.0-incubating
> Environment: IBM jdk 1.8,maven 3.3.9

> 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
