Subject [jira] [Created] (HDFS-8871) Decommissioning of a node with a failed volume may not start
Date Thu, 06 Aug 2015 22:06:05 GMT
Kihwal Lee created HDFS-8871:
--------------------------------

             Summary: Decommissioning of a node with a failed volume may not start
                 Key: HDFS-8871
                 URL: https://issues.apache.org/jira/browse/HDFS-8871
             Project: Hadoop HDFS
          Issue Type: Bug
    Affects Versions: 2.6.0
            Reporter: Kihwal Lee
            Priority: Critical


Since staleness may not be properly cleared, a node with a failed volume may not actually
get scanned for block replication. Nothing is being replicated from these nodes.

This bug does not manifest unless the datanode has a unique storage ID per volume.
