Subject [jira] Updated: (MAPREDUCE-1030) Reduce tasks are getting starved in capacity scheduler
Date Mon, 05 Oct 2009 05:21:40 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-1030?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Hemanth Yamijala updated MAPREDUCE-1030:

    Attachment: MAPREDUCE-1030-5.patch

This patch updates documentation in CapacityTaskScheduler and TestCapacityScheduler to be
in sync with the new behavior of assigning a map and reduce with each heartbeat.

I did these changes along with the code review, as I felt that it would be easier to make
these changes rather than provide them as feedback, which would have made the feedback unnecessarily

I do have other review comments that are not related to synching up the documentation that
I will raise in a separate comment.
