HRegionServer hangs upon exit due to DFSClient Exception
--------------------------------------------------------
Key: HADOOP-2526
URL: https://issues.apache.org/jira/browse/HADOOP-2526
Project: Hadoop
Issue Type: Bug
Components: contrib/hbase
Affects Versions: 0.15.0
Environment: CentOS 5
Reporter: Chris Kline
Priority: Minor
Several HRegionServers hang around indefinitely well after the HMaster has
exited. This was triggered executing $HBASE_HOME/bin/stop-hbase.sh. The
HMaster exists fine, but here is what happens on one of the HRegionServers:
