             Summary: rmadmin -replaceLabelsOnNode does not correctly parse port
                 Key: YARN-2723
             Project: Hadoop YARN
          Issue Type: Bug
          Components: client
            Reporter: Phil D'Amore

There is an off-by-one issue in (line 457):

port = Integer.valueOf(nodeIdStr.substring(nodeIdStr.indexOf(":")));

should probably be:

port = Integer.valueOf(nodeIdStr.substring(nodeIdStr.indexOf(":")+1));

Currently attempting to add a label to a node with a port specified looks like 

[yarn@ip-10-0-0-66 ~]$ yarn rmadmin -replaceLabelsOnNode,test-label
replaceLabelsOnNode: For input string: ":45454"
Usage: yarn rmadmin [-replaceLabelsOnNode [node1:port,label1,label2 

It appears to be trying to parse the ':' as part of the integer because the 
substring index is off.
