I mixed DirectPipelineRunner ("old" local runner), and InProcessPipelineRunner ("new" local runner) ;) We should remove the DirectPipelineRunner to avoid confusion. WDYT ? We would like to do this soon, but there are some snags. As a preparation step, Thomas swapped the default runner from Direct to InProcess. (#178 <https://github.com/apache/incubator-beam/pull/178>) However, testing unfortunately exposed some issues with the InProcess runner. (Actually, I should say "fortunately" because the tests caught it! Yay!) So we had to roll it back. (#198 <https://github.com/apache/incubator-beam/pull/198>) Once we improve the InProcess runner, we can re-do the default swap. After the swap, once the tests keep passing for a few days, we do indeed intend to delete the current Direct pipeline runner and replace it with the current InProcess runner.

You can try using the InProcessPipelineRunner, which is the re-write of local execution that provides support for unbounded PCollections and better checking against the Beam Model. (We'll be renaming this to the DirectPipelineRunner in the near future to avoid having both as soon as the functionality of the InProcessPipelineRunner is complete.)

It's now fixed, so if you take a latest nightly build, or build master, it should work. As workaround, you can also limit the number of message consumed from Kafka (and so work with bounded).
