Time Spent: 10m
Remaining Estimate: 0h
> Behavior requires documentation: Pipeline can't run before fusion

> Key: BEAM-6762
> URL: https://issues.apache.org/jira/browse/BEAM-6762
> Project: Beam
> Issue Type: Task
> Components: runner-core
> Reporter: Kyle Weaver
> Priority: Minor
> Labels: documentation
> Time Spent: 10m
> Remaining Estimate: 0h

> When I was prototyping a portable runner, I tested using a trivial pipeline:
> {noformat}
> PCollection<byte[]> result = pipeline.apply("impulse", Impulse.create());
> PAssert.thatSingleton(result).isEqualTo(new byte[]{});
> {noformat}
> When I tried traversing this pipeline, I found that the URN for the transform
> PAssert$0 was strangely missing. Turns out GreedyPipelineFuser solves this
> problem. I don't know why this is so, but I think this behavior should at
> least be documented in the [runner authoring
> guide|https://beam.apache.org/contribute/runner-guide/#pipeline] to save
> future runner authors some debugging.
