>                 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.
