Description
We've seen jobs using portability start off in a healthy state, but then eventually get stuck and hang on bundle registration. We see error logs from the worker harness:
Processing stuck in step s01 for at least 06h30m00s without outputting or completing in state finish at sun.misc.Unsafe.park(Native Method) at java.util.concurrent.locks.LockSupport.park(LockSupport.java:175) at java.util.concurrent.CompletableFuture$Signaller.block(CompletableFuture.java:1693) at java.util.concurrent.ForkJoinPool.managedBlock(ForkJoinPool.java:3323) at java.util.concurrent.CompletableFuture.waitingGet(CompletableFuture.java:1729) at java.util.concurrent.CompletableFuture.get(CompletableFuture.java:1895) at org.apache.beam.sdk.util.MoreFutures.get(MoreFutures.java:57) at org.apache.beam.runners.dataflow.worker.fn.control.RegisterAndProcessBundleOperation.finish(RegisterAndProcessBundleOperation.java:277) at org.apache.beam.runners.dataflow.worker.util.common.worker.MapTaskExecutor.execute(MapTaskExecutor.java:85) at org.apache.beam.runners.dataflow.worker.fn.control.BeamFnMapTaskExecutor.execute(BeamFnMapTaskExecutor.java:119) at org.apache.beam.runners.dataflow.worker.StreamingDataflowWorker.process(StreamingDataflowWorker.java:1226) at org.apache.beam.runners.dataflow.worker.StreamingDataflowWorker.access$1000(StreamingDataflowWorker.java:141) at org.apache.beam.runners.dataflow.worker.StreamingDataflowWorker$6.run(StreamingDataflowWorker.java:965) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745)
Looking at the code, it looks like there are no timeouts on the Bundle Registration calls over the FnApi, which contributes to this hanging forever rather than giving a better failure.
This bug report came from a customer running a python streaming pipeline using the new portability framework on Dataflow. Hopefully we can repro on our own in order to link to the job / logs.
