Subject [jira] Commented: (HBASE-3609) Improve the selection of regions to balance; part 2
Date Wed, 09 Mar 2011 06:29:59 GMT

    [ https://issues.apache.org/jira/browse/HBASE-3609?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13004393#comment-13004393

stack commented on HBASE-3609:
------------------------------

Patch looks good Ted.  How you propose we add it in?  It'd be put in place instead of the
randomizing balancing?  Or should it be a configuration where we load different balancing
algoritms.  For example, I can imagine that some would like to balance based off requests/second....
rather than region count. 

Oh, you think a test would make sense for your stuff?

Good stuff.
