Wei-Chiu Chuang commented on HDFS-15982:
----------------------------------------
So – essentially we change the default behavior of webhdfs delete operation.
This is a big incompatible change. If we think this should be part of 3.4.0,
risking our compatibility guarantee (which I think makes sense, given how many
times I was involved in accidental data deletion), I think it can be part of
3.3.1. We traditionally regard 3.3.0 as non-production ready, so making an
incompat change in 3.3.1 probably is justifiable.
You will want to make sure to add a release note. Also, we should consider
making the delete behavior of DistributedFileSystem consistent with
webhdfs/httpfs (i.e. do not skip trash by default)
Thoughts?
(BTW, thanks for involving me. I suspect it's going to break some of our
applications/integration tests, so having a little more preparedness is good)

> If we delete the data from the Web UI then it should be first moved to
> configured/default Trash directory and after the trash interval time, it
> should be removed. currently, data directly removed from the system[This
> behavior should be the same as CLI cmd]
> This can be helpful when the user accidentally deletes data from the Web UI.
> Similarly we should provide "Skip Trash" option in HTTP API as well which
> should be accessible through Web UI.
