Arpit Agarwal updated HDFS-8392: -------------------------------- Attachment: HDFS-8392-HDFS-7240.01.patch > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
