Subject [jira] [Created] (MAPREDUCE-3779) Create hard and soft limits for job counters
Date Wed, 01 Feb 2012 18:21:02 GMT
Create hard and soft limits for job counters
--------------------------------------------

                 Key: MAPREDUCE-3779
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3779
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: jobtracker, tasktracker
    Affects Versions: 1.0.0, 0.23.0
            Reporter: Dave Shine
            Priority: Minor


The mapreduce.job.counters.limit is not overridable at the job level.  While it is necessary
to limit the number of counters to reduce overhead, there are times when exceeding the limit
is required.  Currently, the only solution is to increase the limit cluster wide.

I would like to see a soft limit set in the mapred-site.xml that can be overridden at the
job level, in addition to the hard limit that exists today.
