[jira] [Created] (YARN-4344) NMs reconnecting with changed capabilities can lead to wrong cluster resource calculations

Varun Vasudev created YARN-4344:
-----------------------------------

             Summary: NMs reconnecting with changed capabilities can lead to wrong cluster resource calculations
                 Key: YARN-4344
                 URL: https://issues.apache.org/jira/browse/YARN-4344
             Project: Hadoop YARN
          Issue Type: Bug
          Components: resourcemanager
    Affects Versions: 2.6.2, 2.7.1
            Reporter: Varun Vasudev
            Assignee: Varun Vasudev
            Priority: Critical


After YARN-3802, if an NM re-connects to the RM with changed capabilities, there can arise situations where the overall cluster resource calculation for the cluster will be incorrect leading to inconsistencies in scheduling.
