Subject [jira] [Created] (YARN-1722) AMRMProtocol should have a way of getting all the nodes in the cluster
Date Thu, 13 Feb 2014 01:56:19 GMT
Bikas Saha created YARN-1722:
--------------------------------

             Summary: AMRMProtocol should have a way of getting all the nodes in the cluster
                 Key: YARN-1722
                 URL: https://issues.apache.org/jira/browse/YARN-1722
             Project: Hadoop YARN
          Issue Type: Bug
    Affects Versions: 2.2.0
            Reporter: Bikas Saha
             Fix For: 2.4.0


There is no way for an AM to find out the names of all the nodes in the cluster via the AMRMProtocol.
An AM can only at best ask for containers at * location. The only way to get that information
is via the ClientRMProtocol but that is secured by Kerberos or RMDelegationToken while the
AM has an AMRMToken. This is a pretty important piece of missing functionality. There are
other jiras opened about getting cluster topology etc. but they havent been addressed due
to a clear definition of cluster topology perhaps. Adding a means to at least get the node
information would be a good first step.
