> This Jira proposes to replace the FsDatasetImpl object lock with a separate
> lock object. Doing so will make it easier to measure lock statistics like
> lock held time and warn about potential lock contention due to slow disk
> operations.
> Right now we can use org.apache.hadoop.util.AutoCloseableLock. In the future
> we can also consider replacing the lock with a read-write lock.
