[jira] [Created] (HBASE-15396) Enhance mapreduce.TableSplit to add encoded region name

Harsh J created HBASE-15396:
-------------------------------

             Summary: Enhance mapreduce.TableSplit to add encoded region name
                 Key: HBASE-15396
                 URL: https://issues.apache.org/jira/browse/HBASE-15396
             Project: HBase
          Issue Type: Improvement
          Components: mapreduce
    Affects Versions: 1.3.0
            Reporter: Harsh J
            Assignee: Harsh J
            Priority: Minor


When troubleshooting HBase-input MR job map failures, the TableSplit's toString() definition comes very handy. However, it still does not tell us directly which region ID it was created for (it does tell us the key and the host, but not the exact region name, so there's a second lookup needed from the UI to find the ID to then check the servers with).

It would be beneficial to have the encoded region name as part of the output, so this extra manual lookup can be avoided. The encoded name is much easier to find events with.
