          Hi Arpit Agarwal, thanks for working on this. Having read the change, it looks good. A minor not introduced by this, but would be good to fix.

          • In the following, it says AutoCloseable wraps ReentrantLock, which isn't accurate. ReentrantLock => Lock.
            /**
             * This is a wrap class of a ReentrantLock. Extending AutoCloseable
             * interface such that the users can use a try-with-resource syntax.
             */
            

          The patch could also be re-based.

          Arpit Agarwal,

          Currently datasetLock is a big lock, which is used to replace original "synchronized" FsDatasetImpl object. For volumeMap, I am thinking whether we could use a separate lock so that we dont' need to contend datasetLock with other thread therefore the performance can be improved. What do you think?

          • volumeMap = new ReplicaMap(this);
            + volumeMap = new ReplicaMap(datasetLock); <------------------
            ...
          • ReplicaMap tempVolumeMap = new ReplicaMap(this);
            + ReplicaMap tempVolumeMap = new ReplicaMap(datasetLock); <---------------------------
            fsVolume.getVolumeMap(tempVolumeMap, ramDiskReplicaTracker);

          Hi Fenghua Hu, that probably makes sense although we may need more analysis to ensure it doesn't introduce synchronization issues.

          This change is meant to fix the immediate regression and keep the behavior consistent with what we had earlier.

          Actually, i opened another JIRA https://issues.apache.org/jira/browse/HDFS-10804 for replicaMap lock issue, but after seeing your fix, i thought we could consider them together in HDFS-10828.

          I agree with you that it makes sense to keep the existing behavior in this fix, and we will use HDFS-10804 to track ReplicaMap issue. Thanks.

          Hi Kai Zheng, sorry I missed this comment.

          In the following, it says AutoCloseable wraps ReentrantLock, which isn't accurate. ReentrantLock => Lock.

          Yes we can fix that separately. Do you want to file a jira?

          Thanks Arpit Agarwal. The minor wasn't new and I thought it could be fixed in HDFS-9668. Ping Jingcheng Du to take care of this.
