hdfs throughput calculation is incorrect in chukwa database
-----------------------------------------------------------
Key: HADOOP-5051
URL: https://issues.apache.org/jira/browse/HADOOP-5051
Project: Hadoop Core
Issue Type: Bug
Environment: Redhat 5.1, Java 6
Reporter: Eric Yang
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.
