Subject [jira] [Created] (YARN-6895) Preemption reservation may cause regular reservation leaks
Date Thu, 27 Jul 2017 19:27:00 GMT
Miklos Szegedi created YARN-6895:
------------------------------------

             Summary: Preemption reservation may cause regular reservation leaks
                 Key: YARN-6895
                 URL: https://issues.apache.org/jira/browse/YARN-6895
             Project: Hadoop YARN
          Issue Type: Bug
          Components: fairscheduler
    Affects Versions: 3.0.0-alpha4
            Reporter: Miklos Szegedi
            Assignee: Miklos Szegedi
            Priority: Blocker


We found a limitation in the implementation of YARN-6432. If the container released is smaller
than the preemption request, a node reservation is created that is never deleted.
