-------------------------------------
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.
