> DataNode support for multiple datasets

> Key: HDFS-8392
> URL: https://issues.apache.org/jira/browse/HDFS-8392
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: datanode
> Reporter: Arpit Agarwal
> Assignee: Arpit Agarwal
> Attachments: HDFS-8392-HDFS-7240.01.patch
>
>
> For HDFS-7240 we would like to share available DataNode storage across HDFS
> blocks and Ozone objects.
> The DataNode already supports sharing available storage across multiple block
> pool IDs for the federation feature. However all federated block pools use
> the same dataset implementation i.e. {{FsDatasetImpl}}.
> We can extend the DataNode to support multiple dataset implementations so the
> same storage space can be shared across one or more HDFS block pools and one
> or more Ozone block pools.
