----------------------------------------------------------

it might due to some random stuff, I tried in thread flink again with 100 worker_threads, and this time it works(I also changed -parallelism=1 instead of -parallelism=2 before, not sure if it's related),

but when I tried separate local flink cluster, it works for some simple pipeline but got stuck for some complex tensorflow transform pipelines

when I tried separate local flink cluster, each time pipeline stuck at different places, I will try confirm it and put more information about where it stucks

> I noticed that without this "–experiments=worker_threads=100", pipeline will stuck,
> The weird thing is, I tried some complex pipeline using the in thread flink method (./gradlew :beam-runners-flink_2.11-job-server:runShadow)
> "–experiments=worker_threads=100" doesn't work, but "–experiments=worker_threads=1000" works fine
> Then I tried the same pipeline using the separate local flink cluster (./gradlew :beam-runners-flink_2.11-job-server:runShadow -PflinkMasterUrl=localhost:8081), flink version is 1.5.6 (other version doesn't work, see BEAM-6915)
> Neither did "–experiments=worker_threads=1000" or "–experiments=worker_threads=10000" work, pipeline stuck at certain stage (shows running in flink UI but won't finish forever)
> any real fix to that? Thanks!
