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.
