Jason Lowe commented on YARN-3554:
----------------------------------

I suggest we go with 3 minutes.  The retry interval is 10 seconds, so we'll get 
plenty of retries in that time if the failure is fast (e.g.: unknown host, 
connection refused) and still get a few retries in if the failure is slow 
(e.g.: connection timeout).

> Default value for maximum nodemanager connect wait time is too high

> The default value for yarn.client.nodemanager-connect.max-wait-ms is 900000 
> msec or 15 minutes, which is way too high.  The default container expiry time 
> from the RM and the default task timeout in MapReduce are both only 10 
> minutes.
