message
-------------------------------------------------------------------------------------
Key: HADOOP-1723
URL: https://issues.apache.org/jira/browse/HADOOP-1723
Project: Hadoop
Issue Type: Bug
Components: contrib/hbase
Reporter: stack
Assignee: stack
Priority: Trivial
If master tells cluster to shut down, currently region servers hang on the
exit. They are trying return to the exited-master a report that they are on
the way out. This report should not be sent in this scenario. Here's a log
excerpt:
