Junping Du updated HDFS-8584:
-----------------------------
Target Version/s: (was: 2.8.0)
> Support using ramfs partitions on Linux
> ---------------------------------------
>
> Key: HDFS-8584
> URL: https://issues.apache.org/jira/browse/HDFS-8584
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: datanode
> Affects Versions: 2.7.0
> Reporter: Arpit Agarwal
> Assignee: Arpit Agarwal
>
> Now that the bulk of work for HDFS-6919 is complete the memory limit
> enforcement uses the {{dfs.datanode.max.locked.memory}} setting and not the
> RAM disk free space availability.
> We can now use ramfs partitions. This will require fixing the free space
> computation and reservation logic for transient volumes.
