---------------------------------------
{quote}I think changes to the CLI is going to be trouble as there's some
guarantees of consistency over time, with command line, behaviour and of output.

I agree on this [~ste...@apache.org]. However, if we think about this case, we
already have *fs.trash.interval* to decide whether delete operation should keep
files in trash at least until trash interval expires. Now we have another
decision making param *-skipTrash* at command line. If skipTrash is really
required, we should provide such option in UI as well? (a new button along side
delete, with name: *skip-trash* maybe) provided we will have trash support
through web ui as well with HDFS-15982. But perhaps skipTrash is redundant to
override decision already configured by fs.trash.interval? Maybe yes, maybe
not. If yes, we can gradually nullify it's effect internally and with next
major release remove the support (with big enough release notes for users). If
not, we should have it in ui as well. Thoughts?
