Fixup of "missing" daughters on split is too aggressive
-------------------------------------------------------
Key: HBASE-3026
URL: https://issues.apache.org/jira/browse/HBASE-3026
Project: HBase
Issue Type: Bug
Components: master
Reporter: stack
Fix For: 0.90.0
There is a bug in how we check for whether the daughters mentioned in parent
region are present in .META. The check is done when we are processing a server
shutdown. We're making the mistake of checking for presence of the daughter in
the list of regions that used to live on the crashed server BUT fact of the
matter is is that the daughter could just as well be rebalanced to another
server.
The upshot is that we are inserting into .META. and trying to assign regions
that are already assigned.
