---------------------------------------
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?
