Matthew Jacobs created IMPALA-5958:
--------------------------------------

             Summary: Remove duplication of 'yarn-extras' AllocationFileLoaderService
                 Key: IMPALA-5958
                 URL: https://issues.apache.org/jira/browse/IMPALA-5958
             Project: IMPALA
          Issue Type: Improvement
          Components: Frontend
    Affects Versions: Impala 2.11.0
            Reporter: Matthew Jacobs
            Priority: Minor


In IMPALA-5920, some Yarn code that is used by Impala admission control is brought into the Impala codebase.

In the code review, [~zamsden] pointed out that the AllocationFileLoaderService thread for monitoring the fair-scheduler.xml file for changes could be removed if the RequestPoolService used the impala.util.FileWatcherService. See https://gerrit.cloudera.org/#/c/8035/4/common/yarn-extras/src/main/java/org/apache/impala/yarn/server/resourcemanager/scheduler/fair/AllocationFileLoaderService.java@103
