[jira] [Created] (MAPREDUCE-5074) Remove limits on number of counters and counter groups in MapReduce

Ravi Prakash created MAPREDUCE-5074:
---------------------------------------

             Summary: Remove limits on number of counters and counter groups in MapReduce
                 Key: MAPREDUCE-5074
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5074
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: mr-am, mrv2
    Affects Versions: 2.0.3-alpha, 3.0.0, 0.23.6
            Reporter: Ravi Prakash


Can we please consider removing limits on the number of counters and counter groups now that it is all user code? Thanks to the much better architecture of YARN in which there is no single Job Tracker we have to worry about overloading, I feel we should do away with this (now arbitrary) constraint on users' capabilities. Thoughts?
