----------------------------------
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.
