close_region shell command breaks region
----------------------------------------
Key: HBASE-3267
URL: https://issues.apache.org/jira/browse/HBASE-3267
Project: HBase
Issue Type: Bug
Components: master, regionserver, shell
Affects Versions: 0.90.0
Reporter: Todd Lipcon
Priority: Critical
It used to be that you could use the close_region command from the shell to
close a region on one server and have the master reassign it elsewhere. Now if
you close a region, you get the following errors in the master log:
