Zhihong Yu commented on HBASE-5677:
-----------------------------------
The new method has traces of the existing method:
{code}
+ public boolean isMasterAvailable()
+ throws MasterNotRunningException, ZooKeeperConnectionException {
{code}
We should wait for other reviewers' comment about proper naming.
As always, please provide patch for trunk, 0.94 and 0.92.
Attaching patch for trunk would allow Hadoop QA to run.
