      What is new in HADOOP-5051 : - Added macro token subsitution for sum(table_name) - Added correct hdfs throughput aggregation SQL macros.

      Description

      The SQL statement to calculate hdfs throughput is incorrect. The correct algorithm is to calculate metrics rate for individual datanode then sum up of all datanode's rate to get the total throughput for the cluster.
