Subject [jira] [Created] (MAPREDUCE-4027) Document the minimum-allocation-mb configurations
Date Fri, 16 Mar 2012 21:41:35 GMT
Document the minimum-allocation-mb configurations
-------------------------------------------------

                 Key: MAPREDUCE-4027
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4027
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: resourcemanager
    Affects Versions: 0.23.3
            Reporter: Harsh J
            Assignee: Harsh J
            Priority: Minor


None of the current yarn.scheduler.fifo.minimum-allocation-mb and yarn.scheduler.capacity.minimum-allocation-mb
are documented anywhere. Without knowledge of these params, one can't change the default allocations.
And the default allocations are pretty high btw (MAPREDUCE-4026).

We should document these in the Cluster Setup page at least.
