Eli Reisman commented on GIRAPH-82:
-----------------------------------
Should we extend this JIRA to other areas where CLI inputs are important, now
with some of the examples being recently separated from their embedded IO
formats in favor of command-line selection options?
Seems like the idea is to decouple the Vertices people write from the IO
formats they use (or reuse) as much as possible for application code, as a
future best practice? This might also allow us to do things to the standard
reusable IO formats to make the generic strong typing easier to deal with for
application writers as time goes by.

> Currently if no outputformat is specified we default to
> ImmutableOutputCommitter, essentially piping the results of the work out to
> /dev/null. This is a useful output option in some cases, but the default
> probably shouldn't be to throw away work. Making outputformat a required
> option and providing DevNullOutputFormat, or whatever, would likely save some
> surprise from users.
