Subject [jira] Updated: (HADOOP-1429) RPC Server won't go quietly
Date Fri, 25 May 2007 17:00:22 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-1429?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Doug Cutting updated HADOOP-1429:
---------------------------------

    Status: Open  (was: Patch Available)

We should not change the log level.  DEBUG-level messages are normally not printed, and, if
a thread exits unexpectedly, we want something logged.  The problem here is that InterruptedException
isn't unexpected.  The problem with the first patch is that might be other calls that throw
InterruptedException.  So adding a 'catch IOException' clause at the outer level would be
preferable.  Even then, we might still log it if 'running' is not false, since that's the
only case where we expect it.
