      Description

      This JIRA proposes extending HDFS to provide replicated block storage capabilities using Storage Containers. This is would allow users to run unmodified programs that assume that they are running on a posix file system.

      With this extension, HDFS can be used like a block store. For example, YARN jobs could mount and use a volume at will. This is made possible by leveraging Storage Containers and will share the storage layer with Ozone and HDFS in future.

      Please see the attached design document for more details on this proposal.
