Subject [jira] Commented: (HBASE-3609) Improve the selection of regions to balance; part 2
Date Thu, 10 Mar 2011 05:19:59 GMT

    [ https://issues.apache.org/jira/browse/HBASE-3609?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13004967#comment-13004967
] 

Ted Yu commented on HBASE-3609:
-------------------------------

The goal of 3609-alternate.txt is to balance the 'ages' (reflected by sum of region Ids) of
regions across region servers.
Currently HServerLoad doesn't contain HRegionInfo information. This makes validating the above
goal less straightforward.
