      Description

      A few problem with the aggregation SQL statements:

      hdfs throughput should be calculated by doing two level aggregation:

      First, calculate the rate for hadoop datanode metrics with accumulated vales.
      Second, sum up all datanode rate to provide a single number to represent the current cluster performance.

      Disable hod jobs utilization measurement - The data provide a rough view of the cluster performance but mostly inaccurate.
      Disable user utilization measurement generated from hod job - The data is generated from hod job metrics, and it's mostly inaccurate.
