> The IPC layer will retry connection timeouts automatically (see Client.java), 
> but we are also retrying them with YARN's RetryPolicy put in place when the 
> NM proxy is created.  This causes a two-level retry mechanism where the IPC 
> layer has already retried quite a few times (45 by default) for each YARN 
> RetryPolicy error that is retried.  The end result is that NM clients can 
> wait a very, very long time for the connection to finally fail.
