Wangda Tan commented on YARN-1197:
----------------------------------
I totally agree with you, I'll work out a plan considered increase/decrease an
available container (allocated/running) with RM-AM-NM communication, will keep
you posted. Thanks.

> Components: api, nodemanager, resourcemanager
> Affects Versions: 2.1.0-beta
> Reporter: Wangda Tan

> container, which can make us incrementally ask resources, merge them to a
> bigger one, and launch our processes. The user scenario is described in the
