--------------------------------------
Summary: Counters that track max values
Key: MAPREDUCE-4709
URL: https://issues.apache.org/jira/browse/MAPREDUCE-4709
Project: Hadoop Map/Reduce
Issue Type: New Feature
Reporter: Jeremy Lewi
Priority: Minor
A nice feature to help monitor MR jobs would be mapreduce counters that track
the maximum of some metric across all workers. These trackers would work just
like regular counters except it would track the max value of all arguments
passed to the "increment" function as opposed to summing them.
