Steve Loughran commented on HADOOP-16140:
-----------------------------------------
bq. > TestTrash:L509. Dont downgrade an exception to a log, just rethrow
bq. In this case I was copying the pattern that already exists in this (rather
large) test method where the above is used quite a few times. I wonder if its
best to stick with what is there rather than doing something different for this
one additional test?
well. the other tests are probably broken. If an operation fails, the test
should throw an exception so it is reported as a failure.
> 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.
