Allan Yang updated HBASE-21003:
-------------------------------
Description:
TestSplitOrMergeStatus.testSplitSwitch() is flaky because :
1. Set the split switch to false
2. Split the region, expect nothing happen
3. Set the split switch to true, but since the last split request may not start
yet, so setting the switch to true may lead to the last split success
4. Split the same region again, expect split success. But since the last split
operation may already successful, this one will fail
Maybe we should wait for a while between 2 and 3.
