Subject Re: Help writing a YARN application
Date Mon, 23 Sep 2013 23:46:46 GMT
I looked at your code, it's using really old apis/protocols which are significantly different
now. See hadoop-2.1.0-beta release for latest apis/protocols.

Also, you should really be using yarn client module rather than raw protocols.

See https://github.com/hortonworks/simple-yarn-app for a simple example.

thanks,
Arun
