[jira] [Created] (YARN-7622) Allow fair-scheduler configuration on HDFS

Greg Phillips created YARN-7622:
-----------------------------------

             Summary: Allow fair-scheduler configuration on HDFS
                 Key: YARN-7622
                 URL: https://issues.apache.org/jira/browse/YARN-7622
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: fairscheduler, resourcemanager
            Reporter: Greg Phillips
            Assignee: Greg Phillips
            Priority: Minor


The FairScheduler requires the allocation file to be hosted on the local filesystem on the RM node(s). Allowing HDFS to store the allocation file will provide improved redundancy, more options for scheduler updates, and RM failover consistency in HA.
