Subject [jira] [Created] (YARN-1695) Implement the rest (writable APIs) of RM web-services
Date Fri, 07 Feb 2014 18:22:22 GMT
Vinod Kumar Vavilapalli created YARN-1695:
---------------------------------------------

             Summary: Implement the rest (writable APIs) of RM web-services
                 Key: YARN-1695
                 URL: https://issues.apache.org/jira/browse/YARN-1695
             Project: Hadoop YARN
          Issue Type: New Feature
            Reporter: Vinod Kumar Vavilapalli
            Assignee: Vinod Kumar Vavilapalli


MAPREDUCE-2863 added the REST web-services to RM and NM. But all the APIs added there were
only focused on obtaining information from the cluster. We need to have the following REST
APIs to finish the feature
 - Application submission/termination (Priority): This unblocks easy client interaction with
a YARN cluster
 - Application Client protocol: For resource scheduling by apps written in an arbitrary language.
Will have to think about throughput concerns
 - ContainerManagement Protocol: Again for arbitrary language apps.

One important thing to note here is that we already have client libraries on all the three
protocols that do some some heavy-lifting. One part of the effort is to figure out if they
can be made any thinner and/or how web-services will implement the same functionality.
