TaskTracker shutting down
UndeclaredThrowableException when TaskTracker shutting down
-----------------------------------------------------------
Key: HADOOP-1333
URL: https://issues.apache.org/jira/browse/HADOOP-1333
Project: Hadoop
Issue Type: Bug
Components: ipc
Affects Versions: 0.13.0
Reporter: Nigel Daley
We've been seeing this exception in unit tests on Windows since HADOOP-1191 was committed. For instance in TestMiniMRClasspath.

It doesn't seem to cause the tests to fail, but it is logged as an error when a TaskTracker is being shutdown.
