[jira] [Created] (IMPALA-5920) Remove admission control dependency on YARN resourcemanager

Matthew Jacobs created IMPALA-5920:
--------------------------------------

             Summary: Remove admission control dependency on YARN resourcemanager
                 Key: IMPALA-5920
                 URL: https://issues.apache.org/jira/browse/IMPALA-5920
             Project: IMPALA
          Issue Type: Bug
          Components: Frontend
    Affects Versions: Impala 2.10.0
            Reporter: Matthew Jacobs
            Assignee: Matthew Jacobs
            Priority: Critical


Impala's admission controller relies on the YARN fair-scheduler.xml for configuration. That configuration is loaded using YARN directly (ie. as a library by the frontend). In Hadoop 3, a number of changes were made to the YARN resourcemanager which break Impala. While we eventually want to rethink the admission control configuration (IMPALA-4159), in the meantime we at least should avoid using unsupported YARN APIs.
