Harsh J updated HDFS-1847:
--------------------------
Fix Version/s: (was: 0.24.0)
> Datanodes should decomission themselves on volume failure
> ---------------------------------------------------------
>
> Key: HDFS-1847
> URL: https://issues.apache.org/jira/browse/HDFS-1847
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: data-node
> Reporter: Eli Collins
>
> A DN should decommission itself rather than shutdown whenever the configured
> threshold of volume failures (dfs.datanode.failed.volumes.tolerated) has been
> reached. This allows the namenode to distinguish between a datanode that
> might not come back up soon (and will need replication) vs one that is just
> restarting.
