Subject [jira] [Commented] (HBASE-10127) support balance table
Date Thu, 12 Dec 2013 21:39:07 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10127?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13846770#comment-13846770

Lars Hofhansl commented on HBASE-10127:
---------------------------------------

What I meant is that maybe we don't need this in 0.94 either -> either the balancer already
balances by table, or this command is a no-op anyway

Only if there is a specific issue with the balancer not doing the right thing should either
fix the specific problem or have this as a crutch.

> 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?
