             Summary: Add an option to have strict number of mapper per job in 
HBase Streaming
                 Key: HBASE-9896
                 URL: https://issues.apache.org/jira/browse/HBASE-9896
             Project: HBase
          Issue Type: New Feature
          Components: mapreduce
    Affects Versions: 0.89-fb
            Reporter: Rishit Shroff
            Assignee: Rishit Shroff
            Priority: Minor
             Fix For: 0.89-fb


Currently there is only one configuration knob available for controlling the 
number of mappers per job in HBase Streaming. The current option is number of 
mappers per region. This options tries to maintain the locality for the mapper 
and the region servers.

However, in certain certain scenarios where the table has a higher number of 
regions, the number of mapper/region can lead to explosion of the number of 
mappers. Hence, we need one more option to control the strict number of mappers 
per job.
