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.
