----------------------------------

             Summary: DataNode deadlocks after running hdfs mover
                 Key: HDFS-9783
                 URL: https://issues.apache.org/jira/browse/HDFS-9783
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: datanode
    Affects Versions: 2.6.0
            Reporter: David Watzke


We're running CDH 5.4.4 (with Hadoop 2.6.0). Recently we've added 800T of ARCHIVE storage,
marked some data (16T * 2 repl. factor) as "COLD" and ran the hdfs mover to enforce the storage
policy.

After a few minutes, the mover hangs and a few datanodes hang as well.
