sandflee commented on YARN-4495:
--------------------------------

 the main problem is we couldn't pass containerId to 
invaildResourceRequestException. we could convert containerId to String and 
pass to it, but seems a little trick.

> add a way to tell AM container increase/decrease request is invalid

> now RM may pass InvalidResourceRequestException to AM or just ignore the 
> change request, the former will cause AMRMClientAsync down. and the latter 
> will leave AM waiting for the relay.
