Steve Loughran commented on HDFS-9913:
--------------------------------------
correct, it just does filesystem.delete(). I think the docs should be updated.
Moving to rename to ~/.trash will destroy performance when working with object
stores.
> DispCp doesn't use Trash with -delete option
> --------------------------------------------
>
> Key: HDFS-9913
> URL: https://issues.apache.org/jira/browse/HDFS-9913
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: distcp
> Affects Versions: 2.6.0
> Reporter: Konstantin Shaposhnikov
> Assignee: John Zhuge
> Priority: Major
>
> Documentation for DistCp -delete option says
> ([http://hadoop.apache.org/docs/current/hadoop-distcp/DistCp.html]):
> | The deletion is done by FS Shell. So the trash will be used, if it is
> enable.
> However it seems to be no longer the case. The latest source code
> (https://svn.apache.org/repos/asf/hadoop/common/trunk/hadoop-tools/hadoop-distcp/src/main/java/org/apache/hadoop/tools/mapred/CopyCommitter.java)
> uses `FileSystem.delete` and trash options seems to be not applied.
