Duo Zhang commented on HBASE-19838:
-----------------------------------
[~stack] FYI. This UT fails stably for me.
Use a mocked HMaster implementation to hold in initClusterSchemaService and
then we kill all the RSes and then let it go on. The UT will hang in
HBaseTestingUtility.shutdownMiniCluster.
> Can not shutdown backup master cleanly when it has already tried to become
> the active master

> This is the root cause that why TestZooKeeper hangs.
> Open a new issue to introduce a UT which can reproduce the problem stably so
> that we can fix the TestZooKeeper since it is not designed to test this
> problem.
