      Description

      https://github.com/apache/hive/blob/ac6b2a3fb195916e22b2e5f465add2ffbcdc7430/ql/src/java/org/apache/hadoop/hive/ql/exec/MapOperator.java#L573-L582

      This class emits a log message every time it a certain number of records are processed, but it does not print a final count.

      Overload the MapOperator class's closeOp method to print a final log message providing the total number of rows read by this mapper.
