> 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.
