Jeffrey Zhong commented on HBASE-10101:
---------------------------------------
[~jxiang] There are some issues in the test utility shutdown and that's why I
made change to make sure we have a clean cluster restart:
1) We close ZookeeperWatcher before we shutdown a cluster so the shut down may
leave unclean state because ZK is already closed and shutdown code has no way
talk to ZK.
2) ZK Ephemeral nodes take a little bit time be cleaned depends on how
ZooKeeper handles zk session timeout. Therefore, if a cluster restarts so
quick, the following cluster start up may see stale ZK nodes which may cause
the issue.
> testOfflineRegionReAssginedAfterMasterRestart times out sometimes.
