Subject [jira] [Commented] (HBASE-7932) Do the necessary plumbing for the region locations in META table and send the info to the RegionServers
Date Sun, 12 May 2013 12:19:16 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7932?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13655523#comment-13655523
] 

Hudson commented on HBASE-7932:
-------------------------------

Integrated in hbase-0.95-on-hadoop2 #96 (See [https://builds.apache.org/job/hbase-0.95-on-hadoop2/96/])
    HBASE-7932. Introduces Favored Nodes for region files. Adds a balancer called FavoredNodeLoadBalancer
that will honor favored nodes in the process of balancing but the balance operation is currently
a no-op (Devaraj Das) (Revision 1481477)

     Result = FAILURE
