Subject [jira] [Commented] (HBASE-15504) Fix Balancer in 1.3 not moving regions off overloaded regionserver
Date Wed, 13 Apr 2016 16:45:25 GMT

Elliott Clark commented on HBASE-15504:
---------------------------------------

Not really. Though I can tell you that the balancer is broken by HBASE-14604 on production
clusters and clusters running just ITBLL.

> 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.
