Work Description: Hannah-Jiang commented on pull request #9218:
[BEAM-7874] Fnapi bugfix - it only supports up to 10 workers
URL: https://github.com/apache/beam/pull/9218
We hard coded max_threads=10 for grpc servers. In case we pass a
direct_num_workers greater than 10, pipeline hangs because not all workers can
connect to the runner. Pass num_workers to grpc server instead of hard code it
to 10.
