Appy commented on HBASE-19803:
------------------------------
So to iterate faster in trying to understand what/when/how this happens, i
switched to hbase-http module, added System.exit(0) at the end of
TestGlobalFilter#testServletFilter.
forkedProcessTimeoutInSeconds=10sec (should be fine since no http test takes
more than 4 sec on my machine, see list below)
reuseForks=false (that's our default in root pom)

> Key: HBASE-19803
> URL: https://issues.apache.org/jira/browse/HBASE-19803
> Project: HBase
> Issue Type: Bug
> Reporter: Duo Zhang
> Priority: Major
>
> 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.
