-------------------------------------

             Summary: On region jump ClientScanners should get next row start key instead
of a skip.
                 Key: HBASE-12761
                 URL: https://issues.apache.org/jira/browse/HBASE-12761
             Project: HBase
          Issue Type: Improvement
            Reporter: Jurriaan Mous
            Assignee: Jurriaan Mous


While working on async scanner I had some trouble with the extra RPC calls that happen to
let the Scanner advance 1 row so it skips the last already known row. 
This RPC call can be avoided by letting the start key be the last row with an appended 0.
This saves quite some logic from the scanners and improves performance by saving extra RPC
calls.
