Jens Rabe created YARN-3135:

             Summary: There should be an easier way to submit Java-based YARN 
                 Key: YARN-3135
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: api
            Reporter: Jens Rabe

Since YARN is designed to not only work with Java, it is quite difficult and 
cumbersome to correctly setup a YARN application. For Java-based ones, it 
should be easier; there should be something like the MR2 Job API. My proposal 
is the following:
# Have a basic Job / Application object, e.g. YarnApplication, which could be 
instantiated and configured the following:
final Configuration conf = ...
final YarnApplication app = YarnApplication.getInstance(conf);
# There should be a means to send and receive messages between container and 
# The container should be able to report progress and state to the AppMaster
# Bonus: A simplified WebAppMaster should start a web application and have its 
URL automatically proxied when run
