Subject [jira] [Created] (YARN-9202) RM does not track nodes that are in the include list and never register

Kuhu Shukla created YARN-9202:
---------------------------------

             Summary: RM does not track nodes that are in the include list and never register
                 Key: YARN-9202
                 URL: https://issues.apache.org/jira/browse/YARN-9202
             Project: Hadoop YARN
          Issue Type: Bug
    Affects Versions: 2.8.5, 3.0.3, 2.9.2
            Reporter: Kuhu Shukla
            Assignee: Kuhu Shukla


The RM state machine decides to put new or running nodes in inactive state only past the point
of either registration or being in the exclude list. This does not cover the case where a
node is the in the include list but never registers and since all state changes are based
on these NodeState transitions, having NEW nodes be listed as inactive first may help. This
would change the semantics of how inactiveNodes are looked at today. Another state addition
might help this case too.
