> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: datanode
> Affects Versions: HDFS-7240
> Reporter: Arpit Agarwal
> Assignee: Arpit Agarwal
> Attachments: HDFS-8661-HDFS-7240.01.patch,

> {{DataNode#refreshVolumes}} passes the list of NamespaceInfos to each dataset
> when adding new volumes.
> This list should be filtered by the correct NodeType(s) for each dataset.
> e.g. in a shared HDFS+Ozone cluster, FsDatasets would be notified of NN block
> pools and Ozone datasets would be notified of Ozone block pool(s).
