Wang Xu commented on HADOOP-7123:
---------------------------------
Hi folks,
Could HDFS-1362 be treated as a solution on DataNode? Or any other features are
required?
For now, HDFS-457 could stop service of failed disks and HDFS-1362 could add
disks or re-enable disks after repaired them by means of reconfigure DataNode
based on HADOOP-7001.

> This is an umbrella Jira for tracking all the issues and work related for
> handling disk failures across the Hadoop stack. Today, Hadoop handles disk
> failures to some extent but not all the issues. This involves understanding
> both startup and runtime issues related to disk failures in the Hadoop
> components.
> Scope: The initial scope of work will only be for DataNode and TaskTracker
> related disk failure issues.
> Methodology: Injecting disk failures in SCSI layer at various runtime points
> of Hadoop and observing Hadoop's behavior for improvement.
