Summary: Add transfer rate quantile metrics for DataNode reads
Key: HDFS-16917
URL: https://issues.apache.org/jira/browse/HDFS-16917
Project: Hadoop HDFS
Issue Type: Task
Components: datanode
Reporter: Ravindra Dingankar
Currently we have the following metrics for datanode reads.
|BytesRead
BlocksRead
TotalReadTime|Total number of bytes read from DataNode
Total number of blocks read from DataNode
Total number of milliseconds spent on read operation|
We would like to add a new quantile metric calculating the distribution of data
transfer rate for datanode reads.
