> 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
> Assignee: Daryn Sharp
> 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.
