Subject [jira] [Updated] (HBASE-3609) Improve the selection of regions to balance; part 2
Date Tue, 12 Apr 2011 15:29:06 GMT

     [ https://issues.apache.org/jira/browse/HBASE-3609?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Ted Yu updated HBASE-3609:

    Attachment: 3609-double-alternation.txt

This patch combines 3609-empty-RS.txt with my earlier enhancement.
Basically I find the new regions and put them on different underloaded servers. Previously
one underloaded server would be filled up before the next underloaded server is considered.
