Though I can tell you that the balancer is broken by HBASE-14604 on production clusters and clusters running just ITBLL. > Fix Balancer in 1.3 not moving regions off overloaded regionserver > ------------------------------------------------------------------ > > Key: HBASE-15504 > URL: https://issues.apache.org/jira/browse/HBASE-15504 > Project: HBase > Issue Type: Bug > Affects Versions: 1.3.0 > Reporter: Elliott Clark > Assignee: Elliott Clark > Fix For: 2.0.0, 1.3.0, 1.4.0 > > Attachments: HBASE-15504-v3.patch > > > We pushed 1.3 to a couple of clusters. In some cases the regions were assigned VERY un-evenly and the regions would not move after that. > We ended up with one rs getting thousands of regions and most servers getting 0. Running balancer would do nothing. The balancer would say that it couldn't find a solution with less than the current cost. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
