             Summary: Make it easier to access cluster topology information in an AM
                 Key: YARN-435
                 URL: https://issues.apache.org/jira/browse/YARN-435
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Hitesh Shah


ClientRMProtocol exposes a getClusterNodes api that provides a report on all nodes in the cluster including their rack information. 

However, this requires the AM to open and establish a separate connection to the RM in addition to one for the AMRMProtocol.
