New testSideInputsWithMultipleWindows and should DoFnRunner explode if DoFn contains a side input ?

[Amit Sela]

Hi all,

Yesterday a new test was added to ParDoTest suite:
"testSideInputsWithMultipleWindows".
To the best of my understanding, it's meant to test sideInputs for elements
in multiple windows (unexploded).

The Spark runner uses the DoFnRunner (Simple) to process DoFns, and it will
explode compressed elements only if it's "tagged" as "Observes Window".

Should it also explode if it has sideInputs ?

Thanks,
Amit
