> ContainerIO - Storage Management
> --------------------------------
>
> Key: HDDS-48
> URL: https://issues.apache.org/jira/browse/HDDS-48
> Project: Hadoop Distributed Data Store
> Issue Type: Improvement
> Reporter: Hanisha Koneru
> Assignee: Hanisha Koneru
> Priority: Major
> Fix For: 0.2.1
>
> Attachments: ContainerIO-StorageManagement-DesignDoc.pdf, HDDS
> DataNode Disk Layout.pdf, HDDS-48.00.patch, HDDS-48.01.patch
>
>
> We propose refactoring the HDDS DataNode IO path to enforce clean separation
> between the Container management and the Storage layers. All components
> requiring access to HDDS containers on a Datanode should do so via this
> Storage layer.
> The proposed Storage layer would be responsible for end-to-end disk and
> volume management. This involves running disk checks and detecting disk
> failures, distributing data across disks as per the configured policy,
> collecting performance statistics.
> Attached Design Doc gives an overview of the proposed class diagram.
