--------------------------------------
Hi [~xyao]
For people who knows HDFS well, of cause they can just use commands you
mentioned. I am suggesting from a normal user angle ... they would not know
anything about /user/foo/.Trash at all. Expunge command sets up the expectation
that HDFS provides utilities to manage trash, then it is pretty straightforward
to ask for a command removing all trashes.
> Add a force option for hdfs dfs -expunge to remove all check points
