[ https://issues.apache.org/jira/browse/HAMA-673?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13869042#comment-13869042 ]

Hello guys:
I am a new guy to Hama, I have interest because its performance is much better than mahout from your description. Looks amazing.
And from current code,seems YARN app client part API is done.
But lack of master protocol and container manager part integration.
For YARN, one of its problem is its app and job concept is the same, that means one app master can only work for one job.
So there are some approaches like LAMMA is doing some prestart app pools.
What is our plan, I think its better to keep performance.
Also I would like to do some code work if I can.
Regards,
