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. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
