Description

streaming mobile gaming examples had two issues preventing them from running on DataflowRunner. (1) support for --save_main_session flag was recently added, (2) https://github.com/apache/beam/pull/4455 addresses the usability issue related to combiners.

We can now clean the warnings and test that these examples are actually running on Dataflow.
