> Our project, Pig, exposes FsShell functionality to our end users through a shell command. We want to use this command with no modifications to make sure that whether you work with HDFS through Hadoop or Pig you get identical semantics.
> The main concern that has been recently raised by our users is that there is no way to ignore certain failures that they consider to be benign, for instance, removing a non-existent directory.
> We have 2 asks related to this issue:
> (1) Meaningful error code returned from FsShell (we use java class) so that we can take different actions on different errors
> (2) Unix like ways to tell the command to ignore certain behavior. Here are the commands that we would like to be expanded/implemented:
>    * rm -f
>    * rmdir ---ignore-fail-on-non-empty
>    * mkdir -p
