> Key: YARN-12008
> URL: https://issues.apache.org/jira/browse/YARN-12008
> Project: Hadoop YARN
> Issue Type: Bug
> Components: test, timelineclient

>
> testTimelineReaderRecoversAfterHBaseReturns restarts HBase and shuts the
> mini-cluster down as soon as the reader sees storage up. At that point the
> restarted RegionServer can still be opening regions.
> If the shutdown interrupts a region open, HBase aborts the RegionServer.
> Because of HBASE-30460, the abort halts the JVM 20 minutes later. This
> module runs with forkCount=0, so that JVM is the Maven build: the build
> dies in a later, unrelated module with exit code 1 and no failed test.
> See the attached output log, TestTimelineReaderHBaseDown-output.txt.gz:
> 22:52:02.479 startMiniHBaseCluster returns
> 22:52:02.480 test calls shutdownMiniCluster
> 22:52:02.501 ABORTING region server: Failed to open region ...
> 23:12:02 "Zombie HRegionServer" thread dump, Maven exits 1
> The failure is intermittent; other runs of the same job pass.
> Fix: wait for region assignment to finish after the restart.
> util.startMiniHBaseCluster(1, 1);
> util.waitUntilNoRegionsInTransition();
