[jira] [Commented] (HBASE-10127) support balance table

["Jean-Marc Spaggiari (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-10127?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13845400#comment-13845400 ] 

Jean-Marc Spaggiari commented on HBASE-10127:
---------------------------------------------

Sound good to me.

some extra spaces after
{code}
List<RegionPlan> plans = new ArrayList<RegionPlan>();
       <=== Here
{code}

And here:
{code}
     return getMaster().balance();
   }
+  <=== Here
{code}

For the java code, can we say "Balance table's regions" or "Balance regions of a table"?

getMaster() is deprecated. Any chance to replace it? (Not 100% required for the scope of this patch)

Can you do the trunk version to trigger Hadoop QA?

> HMaster provides a rpc interface : 'balance()' to balance all the regions among region servers in the cluster. Sometimes, we might want to balance all the regions belonging to a table while keeping the region assignments of other tables. This demand may reveal in a shared cluster where we want to balance regions for one application's table without affecting other applications. Therefore, will it be useful if we extend the current 'balance()' interface to only balance regions of the same table?
