Caching localized counter names in mapred.Counters
--------------------------------------------------
Key: MAPREDUCE-1156
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1156
Project: Hadoop Map/Reduce
Issue Type: Improvement
Reporter: Hong Tang
Using YourKit profiling mumak, we found that MissingResourceException was
thrown and caught 1.6 million times in Counters.Group.localize for several
hundred of jobs. The resource bundle look up and costly exception processing
can be easily avoided if we have a global cache of localized counter names.
