Ravi Prakash resolved MAPREDUCE-5074.
-------------------------------------
Resolution: Won't Fix
We can re-open this if we find users compelling us to increase the limits
> 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: 3.0.0, 2.0.3-alpha, 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?
