Subject [jira] Created: (HADOOP-5187) Provide an option to turn off priorities in jobs

Provide an option to turn off priorities in jobs

                 Key: HADOOP-5187
                 URL: https://issues.apache.org/jira/browse/HADOOP-5187
             Project: Hadoop Core
          Issue Type: Improvement
          Components: contrib/fair-share
            Reporter: Hemanth Yamijala
            Priority: Minor

The fairshare scheduler can define pools mapping to queues (as defined in the capacity scheduler
- HADOOP-3445). When used in this manner, one can imagine queues set up to be used by users
who come from disparate teams or organizations (say a default queue). For such a queue, it
makes sense to ignore job priorities and consider the queue as strict FIFO, as it is difficult
to compare priorities of jobs from different users.
