Subject [jira] Issue Comment Edited: (HADOOP-5114) A bunch of mapred unit tests are failing on Windows

bq. I still want to check why exactly is the timeout for accept() required.

It looks like the timeout for accept is not required (tested on Linux). The problem was that
offerService() thread waits on DataXCeiver thread before calling shutdown. We should just
move the 'join' into shutdown().

will check the simple fix on Windows. Note that TestDiskError fails anyway later (for a different
reason, HADOOP-2023), but I just want to make sure that DataNode actually exits in case of
real error.
