Xuan Gong commented on YARN-479:
--------------------------------
minor question : why add Assert response != null ? Trying to test
post-condition here ?
If response == null, what will happen ? I mean, if response == null, the
following code response.getNodeAction() will give error anyway.
> NM retry behavior for connection to RM should be similar for lost heartbeats
