Guanghao Zhang created HBASE-16368:
--------------------------------------
Summary: test*WhenRegionMove in TestPartialResultsFromClientSide
is flaky
Key: HBASE-16368
URL: https://issues.apache.org/jira/browse/HBASE-16368
Project: HBase
Issue Type: Bug
Components: Scanners
Affects Versions: 1.4.0
Reporter: Guanghao Zhang
This test fail when Hadoop QA run preCommit:
https://builds.apache.org/job/PreCommit-HBASE-Build/2971/testReport/org.apache.hadoop.hbase/TestPartialResultsFromClientSide/testReversedCompleteResultWhenRegionMove/.
And I found it is in Flaky Tests Dashboard:
http://hbase.x10host.com/flaky-tests/. I run it in my local machine and it may
fail, too.
Test results show that the region location didn't update when scanner callable
get a NotServingRegionException or RegionMovedException.
