Stephen Yuan Jiang commented on HBASE-17764:
--------------------------------------------
The V1 change is local to {{TestMultiSlaveReplication}} test suite; the
{{org.apache.hadoop.hbase.replication.TestSerialReplication.testRegionSplit}}
test failure has nothing to do with this change.
> Solve TestMultiSlaveReplication flakiness

> When I doing testing for a feature I am working on, the
> TestMultiSlaveReplication test was flaky.
> TestMultiSlaveReplication#testMultiSlaveReplication would always pass when
> running alone; however, it would fail occasionally when running with the
> suite (the other test TestMultiSlaveReplication#testZKLockCleaner always run
> first and I suspect that it withhold some zookeeper resource, which caused
> the problem).
> After I set start and shutdown zk cluster before and after each test, I no
> longer see the problem.
