Vinod Kumar Vavilapalli updated HDFS-9038:
------------------------------------------
Target Version/s: 2.7.3 (was: 2.8.0, 2.7.2)
Moving out all non-critical / non-blocker issues that didn't make it out of
2.7.2 into 2.7.3.
> Reserved space is erroneously counted towards non-DFS used.
> -----------------------------------------------------------

> Key: HDFS-9038
> URL: https://issues.apache.org/jira/browse/HDFS-9038
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: datanode
> Affects Versions: 2.7.1
> Reporter: Chris Nauroth
> Assignee: Brahma Reddy Battula
>
> HDFS-5215 changed the DataNode volume available space calculation to consider
> the reserved space held by the {{dfs.datanode.du.reserved}} configuration
> property. As a side effect, reserved space is now counted towards non-DFS
> used. I don't believe it was intentional to change the definition of non-DFS
> used. This issue proposes restoring the prior behavior: do not count
> reserved space towards non-DFS used.
