[jira] [Created] (HBASE-16114) Get regionLocation of only required regions for MR jobs

Thiruvel Thirumoolan created HBASE-16114:
--------------------------------------------

             Summary: Get regionLocation of only required regions for MR jobs
                 Key: HBASE-16114
                 URL: https://issues.apache.org/jira/browse/HBASE-16114
             Project: HBase
          Issue Type: Improvement
          Components: mapreduce
    Affects Versions: 1.2.1
            Reporter: Thiruvel Thirumoolan
            Priority: Minor
             Fix For: 2.0.0, 1.3.0


We should only get the location of regions required during the MR job. This will help for jobs with large regions but the job itself scans only a small portion of it. Similar changes can be seen in MultiInputFormatBase.java.
