[jira] [Commented] (MAPREDUCE-4332) Add a yarn-client module
[ https://issues.apache.org/jira/browse/MAPREDUCE-4332?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13433179#comment-13433179 ]
Jason Lowe commented on MAPREDUCE-4332:
---------------------------------------
Took a quick look, in general looks great. Couple of comments:
* Need to update patch after yarn moved out of mapreduce in YARN-1.
* We should probably mark YarnClient as Public and Unstable or Evolving.
* Would also be nice to add javadocs to the interface methods since most other public interfaces have them.

> I see that we are duplicating (some) code for talking to RM via client API. In this light, a yarn-client module will be useful so that clients of all frameworks can use/extend it.
> And that same module can be the destination for all the YARN's command line tools.
