Major Description
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.
