Lars Hofhansl commented on HBASE-5677:
--------------------------------------
bq. public boolean isMasterRunning() { return !isStopped() && isInitialized();
} But Some class like HMerge,this tool just care the master is running or not.
Is that actually a problem? HMerge would need to wait until the master is
initialized. Seems generally a better a better condition for "running" than
just having the process up.
> The master never does balance because duplicate openhandled the one region
