[jira] Created: (HBASE-2738) Fix TestTimeRangeMapRed verification now that we store multiple versions with same TS

Fix TestTimeRangeMapRed verification now that we store multiple versions with same TS
-------------------------------------------------------------------------------------

                 Key: HBASE-2738
                 URL: https://issues.apache.org/jira/browse/HBASE-2738
             Project: HBase
          Issue Type: Bug
          Components: test
    Affects Versions: 0.21.0
            Reporter: Todd Lipcon
            Assignee: Todd Lipcon


We recently introduced "memstore timestamps" which are internal, and allow a cell to exist twice with the same timestamp, from different puts. TestTimeRangeMapred now fails since it sees both the old and new version of the cells during verification. Setting the max versions of the verification scanner to 1 fixes it.
