      Description

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

      In the code review, Zachary Amsden 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
