Work Description: boyuanzz opened a new pull request #6837: [BEAM-5853]
Possible fix
URL: https://github.com/apache/beam/pull/6837
I'm not sure whether this is a right fix but seems like it works for me to
stop the stuckness.

More information:
For the stuck fnapi worker pipeline, it gets stuck at
[maybeWait](https://github.com/apache/beam/blob/master/runners/google-cloud-dataflow-java/worker/src/main/java/org/apache/beam/runners/dataflow/worker/fn/data/RemoteGrpcPortWriteOperation.java#L165),
and keeps evaluating
[shouldWait](https://github.com/apache/beam/blob/master/runners/google-cloud-dataflow-java/worker/src/main/java/org/apache/beam/runners/dataflow/worker/fn/data/RemoteGrpcPortWriteOperation.java#L111).
I found, the numProcessed should be -1 since it's not supported and the
targetElementsSent should be set to MAX. But the [following else
block](https://github.com/apache/beam/blob/master/runners/google-cloud-dataflow-java/worker/src/main/java/org/apache/beam/runners/dataflow/worker/fn/data/RemoteGrpcPortWriteOperation.java#L129)
will override this logic again, which causes this loop forever.
