Subject [jira] Created: (MAPREDUCE-1500) Improve the way Counters are managed by JobTracker
Date Wed, 17 Feb 2010 15:27:27 GMT
Improve the way Counters are managed by JobTracker
--------------------------------------------------

                 Key: MAPREDUCE-1500
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1500
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: jobtracker
            Reporter: Amar Kamat


Counters typically eat up a considerable amount of JobTracker's heap space. There is also
a considerable heap space wastage due to duplicate Strings in Counters. Some amount of Counters'
storage optimization can help reduce the load on JobTracker's memory.
