Table can't disable
-------------------
Key: HBASE-3892
URL: https://issues.apache.org/jira/browse/HBASE-3892
Project: HBase
Issue Type: Bug
Affects Versions: 0.90.3
Reporter: gaojinchao
Fix For: 0.90.4
In TimeoutMonitor :
if node exists and node state is RS_ZK_REGION_CLOSED
We should send a zk message again when close region is timeout.
in this case, It may be loss some message.
I See. It seems like a bug. This is my analysis.
// disable table and master sent Close message to region server, Region state
was set PENDING_CLOSE
