Hairong Kuang updated HADOOP-270:
---------------------------------
Attachment: datanode_deadlock.patch
The patch moves "join" operation to the end of "offerservice". In addition, it
starts up its data receive server in the beginning of "offerservice" instead of
in the DataNode constructor.

> Attachments: datanode_deadlock.patch
>
> The DataNode class provides a method "shutdown" that can be used to notify a
> data node thread to abort itself gracefully. In addition this method waits
> for its data receiving server to terminate. This may cause possible deadlock
> if the method is called by the data receiving server.
