Subject [jira] [Created] (MAPREDUCE-5680) Reconsider limits
Date Thu, 12 Dec 2013 16:33:07 GMT
Ashutosh Chauhan created MAPREDUCE-5680:

             Summary: Reconsider limits
                 Key: MAPREDUCE-5680
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5680
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: applicationmaster
    Affects Versions: 2.2.0
            Reporter: Ashutosh Chauhan

Limits were first introduced in 0.20.2xx line with the main goal of protecting  jobtracker
from rogue jobs. Now that problem no longer exists in yarn, where each job gets its own MR
AM.  So, its good time now to revisit limits and see which of those still make sense.
