             Summary: Report only local collectors on node upon resync with RM after RM fails over
                 Key: YARN-5841
                 URL: https://issues.apache.org/jira/browse/YARN-5841
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Varun Saxena


As per discussion on YARN-3359, we can potentially optimize reporting of collectors to RM after RM fails over.

Currently NM would report all the collectors known to itself in HB after resync with RM. This would mean many NMs' may pretty much report similar set of collector infos in first NM HB on reconnection. 

This JIRA is to explore how to optimize this flow and if possible, fix it.
