Summary: Add histograms for FSNamesystemLock Metrics
Key: HDFS-10873
URL: https://issues.apache.org/jira/browse/HDFS-10873
Project: Hadoop HDFS
Issue Type: Sub-task
Components: namenode
Reporter: Erik Krogen
Assignee: Erik Krogen
It could be useful to have full histograms for how long operations are holding
the namesystem lock in addition to just rate information. This will, however,
be a large number of emitted metrics and likely require more coordination, so
it may be best to have this be separately configurable from more simple
namesystem lock metrics.
