> I've been noodling on this one for awhile: how to add the ability to execute some code
if and only if one or more targets are created, and have that executed code (optionally) return
one or more new PCollections as a result. I was thinking that this functionality could be
wired in to libraries to do things like bulk loading HBase tables or running Sqoop jobs as
part of Crunch pipelines automatically.
