Chen Liang commented on HDFS-10682: ----------------------------------- The failed test is HDFSCLI, which I don't think has anything to do this patch. And I did not see failure when doing this test locally. > Add metric to measure lock held time in FSDataSetImpl > ----------------------------------------------------- > > Key: HDFS-10682 > URL: https://issues.apache.org/jira/browse/HDFS-10682 > Project: Hadoop HDFS > Issue Type: Improvement > Components: datanode > Reporter: Chen Liang > Assignee: Chen Liang > Attachments: HDFS-10682.001.patch, HDFS-10682.002.patch, > HDFS-10682.003.patch, HDFS-10682.004.patch, HDFS-10682.005.patch > > > Add a metric to measure the time the lock of FSDataSetImpl is held by a > thread.
