Subject RE: Read an empty directory
Date Mon, 18 May 2015 15:34:31 GMT
For the moment, seeing if I can do it with FileSystem.exists(Path) and just omit that particular
input.  Not sure if it will like the globbed fs though.

Not a really clean way; one option would be to call getSize(Configuration) on the underlying
Source you're reading from, and if it returns zero, substitute in a Pipeline.emptyPCollection()
in the place where you would have called

     Is there a way to get my pipeline to load an empty collection instead of throwing an
exception when I pass in a globbed path that doesn't match anything?  It's part of a list
of paths that otherwise match things.
