             Summary: Add update replicaInfo's volume  in LocalReplica#updateWithReplica
                 Key: HDFS-13859
                 URL: https://issues.apache.org/jira/browse/HDFS-13859
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: datanode
    Affects Versions: 3.2.0
            Reporter: liaoyuxiangqin
            Assignee: liaoyuxiangqin


    When DirectoryScanner used diff ScanInfo to check and update with memBlock, i found the LocalReplica#updateWithReplica only update the diskfile path but without replicaInfo's volume. And may be the memblock ' volume is diff with the diskfile path before directory scan, so i think need to update the volume meanwhile,so the replicaInfo's meminfo is consistent with disk storage。The relation code as follows:
{code:java}
public void updateWithReplica(StorageLocation replicaLocation) {
    // for local replicas, the replica location is assumed to be a file.
    File diskFile = null;
    try {
      diskFile = new File(replicaLocation.getUri());
    } catch (IllegalArgumentException e) {
      diskFile = null;
    }

    if (null == diskFile) {
      setDirInternal(null);
    } else {
      setDirInternal(diskFile.getParentFile());
    }
  }
{code}
Thanks all!
