Devaraj K created MAPREDUCE-5195:
------------------------------------

             Summary: Job doesn't utilize all the cluster resources with CombineFileInputFormat
                 Key: MAPREDUCE-5195
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5195
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: job submission
    Affects Versions: 2.0.4-alpha, 0.23.7, 2.0.5-beta
            Reporter: Devaraj K


If we enable delay scheduling in resource manager and the submitted job is using CombineFileInputFormat
then this job is not able to use the all the available resources in the cluster, running most
of the maps in only some nodes and other nodes resources are idle.
