Wangda Tan commented on YARN-1197:
----------------------------------
Bikas,
Thanks for your patiently explains, I just took a look at YARN-898, this really
helps,
I agree RM is much easier than AM to do this. And as you pointed, in our case,
increase an existing container size is as same as merge containers. I support
change this title to something like "increase an existing container size" and
link this to YARN-898.
> Add container merge support in YARN
> -----------------------------------

> Key: YARN-1197
> URL: https://issues.apache.org/jira/browse/YARN-1197
> Project: Hadoop YARN
> Issue Type: Task
> Components: api, nodemanager, resourcemanager
> Affects Versions: 2.1.0-beta
> Reporter: Wangda Tan
>
> Currently, YARN cannot support merge several containers in one node to a big
> 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
> comments.
