URL: https://issues.apache.org/jira/browse/HADOOP-1333
Project: Hadoop
Issue Type: Bug

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.
