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.
