> 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.
