Description

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.
