Thanks, [~StephanEwen]. Changing {noformat}akka.framesize{noformat} to 100 MB resolved my problem, which was a JOIN followed by another JOIN similarly hanging mid-execution when increasing data size.

> The following simple application created from Flink's Java quickstart will hang before execution if the data size is to large. I have tested this on both 0.9.1 and master (7364ce18) and the threshold occurs with
>   $ ./bin/flink run /path/to/blocks/target/blocks-1.0-SNAPSHOT.jar 19
> running in a few seconds while
>   $ ./bin/flink run /path/to/blocks/target/blocks-1.0-SNAPSHOT.jar 20
> seemingly hangs forever.
> I first put this together two months ago so if it is a bug it is not a new bug.

>             data.add(0L);
>         }
>         env.fromCollection(data).output(new DiscardingOutputFormat());
>         System.out.println("Ready to execute ...");
