> 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.
