> Attachments: HADOOP-9655.patch

>
> When one machine power off during running a job ,MRAppMaster find tasks timed out on that host and then call stop container for each container concurrently.
> But the IPC layer did it serially, for each call,the connection time out exception toke a few minutes to raise after 45 times reties. And AM hang for many hours to wait for stopContainer to finish.
> The jstack output file shows that most threads stuck at Connection.addCall waiting for a lock object hold by Connection.setupIOstreams.
> (The setupIOstreams method run slowlly becauseof connection time out during setupconnection.)
