---------------------------------
Summary: Add per-disk latency metrics to DataNode
Key: HDFS-4169
URL: https://issues.apache.org/jira/browse/HDFS-4169
Project: Hadoop HDFS
Issue Type: Improvement
Components: data-node
Affects Versions: 3.0.0
Reporter: Todd Lipcon
Currently, if one of the drives on the DataNode is slow, it's hard to determine
what the issue is. This can happen due to a failing disk, bad controller, etc.
It would be preferable to expose per-drive MXBeans (or tagged metrics) with
latency statistics about how long reads/writes are taking.
