Subject [jira] Updated: (MAPREDUCE-1257) Ability to grab the number of spills
Date Wed, 09 Dec 2009 08:31:18 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-1257?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Chris Douglas updated MAPREDUCE-1257:
-------------------------------------

    Status: Open  (was: Patch Available)

bq. My plan was to backport it into our distribution for 20, where a backport of MAPREDUCE-64
is pretty unlikely since that change is much riskier.

*nod* Makes sense. I'm going to cancel the patch for now, pending a current use case.

Do you count the in-memory merge into the reduce?
