Balancer should not reassign (because of overloading) a region that was just
opened
-----------------------------------------------------------------------------------
Key: HBASE-2240
URL: https://issues.apache.org/jira/browse/HBASE-2240
Project: Hadoop HBase
Issue Type: Bug
Reporter: stack
I'm running a mapreduce job. I see a region split and its daughters come on
line and then 8 seconds later, master judges the regionserver overloaded and so
closes the just-opened region. This messes up clients. They may have just
picked up the new location for their row query and now its moved again and
client has to go hunting anew.
We need to assign the vintage regions first.
I'm going to change balancer slop. Its not sloppy enough and balancing cuts in
too early.
