--------------------------------
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.
