Edward J. Yoon commented on HAMA-673:
-------------------------------------

As I mentioned above, Current YARN module was implemented based on 0.23.1. Our hama-yarn is incompatible with hadoop 2.x. So, first of all, we have to change from 0.23.1 to 2.x stable version.

Then, see the "syncServer = SyncServiceFactory.getSyncServerRunner(jobConf);". Like this, we can design the pluggable messenger service instead of using hadoop RPC. This issue is about it.

Anyway, we have to re-implement the yarn module based on hadoop 2.x version, before thinking about this issue.
