Jonathan Coveney commented on PIG-3183:
---------------------------------------
So obviously this isn't a huge change and it is reasonable to make this work in
the same way that hadoop's removal commands work. The only thing that holds me
back is a sort of innate aversion to "rm *" being able to completely whack your
files. Obviously in any environment this is generally the case but since in the
past this wasn't the case, it just feels...dangerous. Perhaps we want to
consider adding configuration (off by default) that makes it throw an error if
you try to delete more than one file? Would love to hear if anyone else feels
the hesitation that I do.
> rm or rmf commands should respect globbing/regex of path

> Hadoop fs commands support globbing during deleting files/dirs. Pig is not
> consistent with this behavior and seems like we could change rm/rmf commands
> to do the same.
> For eg:
> {code}
> localhost:pig pkommireddi$ ls -ld out*
> drwxr-xr-x 12 pkommireddi SF\domain users 408 Feb 13 01:09 out
> drwxr-xr-x 2 pkommireddi SF\domain users 68 Feb 13 01:16 out1
> drwxr-xr-x 2 pkommireddi SF\domain users 68 Feb 13 01:16 out2
> localhost:pig pkommireddi$ bin/pig -x local
> grunt> rmf out*
> grunt> quit
> localhost:pig pkommireddi$ ls -ld out*
> drwxr-xr-x 12 pkommireddi SF\domain users 408 Feb 13 01:09 out
> drwxr-xr-x 2 pkommireddi SF\domain users 68 Feb 13 01:16 out1
> drwxr-xr-x 2 pkommireddi SF\domain users 68 Feb 13 01:16 out2
> {code}
> Ideally, the user would expect "rmf out*" to delete all of the above dirs.
