Hmaster had crashed as disabling table
--------------------------------------
Key: HBASE-3713
URL: https://issues.apache.org/jira/browse/HBASE-3713
Project: HBase
Issue Type: Bug
Components: master
Affects Versions: 0.90.1
Environment: startup cluster with HA master and 5 datanode.
Reporter: gaojinchao
Operation step:
1, startup cluster with HA master
2, the active master crashed while it is creating table with region
3, backup master become active.
4, I want to drop the table
5, the active master crashed
So the issue is that if a region was closed and disabled when the first master
was running, it won't be assigned anywhere and won't be in transition either
(it's called being in RIT in the code). When the new master comes around, and
disable is called, it does a check to see if the region is in RIT but not if it
was already disabled, and fails on NPE because it's not assigned to anyone.
