Steve Loughran commented on HDFS-14200:
---------------------------------------

seems good, but the patch isn't ready yet.


* Why not just add an option to -expunge. It exists, has tests, documentation, 
etc? 
* add a way to take a filesystem so that I can do this for s3a://bucket1/ . See 
HADOOP-13656
* TestTrash:L509. Dont downgrade an exception to a log, just rethrow

Finally: press the submit button so yetus runs it. No yetus, no review.

> Add emptyTrash option to purge trash immediately

> I have always felt the HDFS trash is missing a simple way to empty the 
> current users trash immediately. We have "expunge" but in my experience 
> supporting clusters, end users find this confusing. When most end users run 
> expunge, they really want to empty their trash immediately and get confused 
> when expunge does not do this.
> This can result in users performing somewhat dangerous "skipTrash" operations 
> on the trash to free up space. The alternative, which most users will not 
> figure out on their own is:
> # Run the expunge command once - this will move the current folder to a 
> checkpoint and remove any old checkpoints older than the retention interval
> # Wait over 1 minute and then run expunge again, overriding fs.trash.interval 
> to 1 minute using the following command hadoop fs -Dfs.trash.interval=1 
> -expunge.
> With this Jira I am proposing to add a extra command, "hdfs dfs -emptyTrash" 
> that purges everything in the logged in users Trash directories immediately.
> How would the community feel about adding this new option? I will upload a 
> patch for comments.
