Zhihong Yu commented on HBASE-5677:
-----------------------------------
There is this method in HMasterInterface:
{code}
/** @return true if master is available */
public boolean isMasterRunning();
{code}
If we introduce isMasterAvailable(), that would create confusion, right ?
> The master never does balance because duplicate openhandled the one region
