Thomas Groh commented on BEAM-136:
----------------------------------
The default collection of runners is obtained by using
ServiceLoader.load(PipelineRunnerRegistrar.class); within the SDK, we use the
@AutoService annotation (com.google.auto.service.AutoService, from Guava) to
register the DataflowPipelineRunner, BlockingDataflowPipelineRunner, and
DirectPipelineRunner, but should automatically pick up any other registrars
located on the classpath.
PR 61 (https://github.com/apache/incubator-beam/pull/61) fixes looking up
runners via a fully qualified class name.
> PipelineOptionsFactory should detect all runners
