Subject [jira] [Comment Edited] (HBASE-19803) False positive for the HBASE-Find-Flaky-Tests job
Date Thu, 25 Jan 2018 01:25:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-19803?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16338516#comment-16338516

-------------------------------------------------------

So that's because we set   {{<forkedProcessTimeoutInSeconds>${surefire.timeout}</forkedProcessTimeoutInSeconds>}}
where surefire.timeout is 900 i.e. 15 min.
I tried setting it to 30 sec, but the tests still keep on running :-/
Edit: So it makes sense, the timeout is to kill rouge forked jvms which don't shutdown themselves.
Whereas in our case, jvm goes away without returned the result to surefire - totally different
thing.

> It reports two hangs for TestAsyncTableGetMultiThreaded, but I checked the surefire output
> https://builds.apache.org/job/HBASE-Flaky-Tests/24830/artifact/hbase-server/target/surefire-reports/org.apache.hadoop.hbase.client.TestAsyncTableGetMultiThreaded-output.txt
> This one was likely to be killed in the middle of the run within 20 seconds.
> https://builds.apache.org/job/HBASE-Flaky-Tests/24852/artifact/hbase-server/target/surefire-reports/org.apache.hadoop.hbase.client.TestAsyncTableGetMultiThreaded-output.txt
> This one was also killed within about 1 minutes.
> The test is declared as LargeTests so the time limit should be 10 minutes. It seems that
the jvm may crash during the mvn test run and then we will kill all the running tests and
then we may mark some of them as hang which leads to the false positive.
