Subject [jira] [Created] (MAPREDUCE-5608) Replace and deprecate mapred.tasktracker.indexcache.mb
Date Tue, 05 Nov 2013 21:19:17 GMT
Sandy Ryza created MAPREDUCE-5608:

             Summary: Replace and deprecate mapred.tasktracker.indexcache.mb
                 Key: MAPREDUCE-5608
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5608
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
    Affects Versions: 2.2.0
            Reporter: Sandy Ryza

In MR2 mapred.tasktracker.indexcache.mb still works for configuring the size of the shuffle
service index cache.  As the tasktracker no longer exists, we should replace this with something
like mapreduce.shuffle.indexcache.mb.
