Just now I try to use the PROCESS environment type, the Flink taskmanager complains about "/tmp/beam-artifact-staging/job_xxx" not found. And I found this directory is only created on the machine with beam job endpoint. I guess maybe I should set the artifact-dir to a hdfs location, but no luck for me:(
I don’t know if the following error message from job endpoint is related when submitting the job. Error from job endpoint: --------------- [grpc-default-executor-0] ERROR org.apache.beam.runners.fnexecution.jobsubmission.InMemoryJobService - Encountered Unexpected Exception for Invocation job_09aa2abd-0bc0-4994-a8b7-130156e4c13c org.apache.beam.vendor.grpc.v1p13p1.io.grpc.StatusException: NOT_FOUND at org.apache.beam.vendor.grpc.v1p13p1.io.grpc.Status.asException(Status.java:534) at org.apache.beam.runners.fnexecution.jobsubmission.InMemoryJobService.getInvocation(InMemoryJobService.java:341) at org.apache.beam.runners.fnexecution.jobsubmission.InMemoryJobService.getStateStream(InMemoryJobService.java:262) at org.apache.beam.model.jobmanagement.v1.JobServiceGrpc$MethodHandlers.invoke(JobServiceGrpc.java:770) at org.apache.beam.vendor.grpc.v1p13p1.io.grpc.stub.ServerCalls$UnaryServerCallHandler$UnaryServerCallListener.onHalfClose(ServerCalls.java:171) at org.apache.beam.vendor.grpc.v1p13p1.io.grpc.PartialForwardingServerCallListener.onHalfClose(PartialForwardingServerCallListener.java:35) at org.apache.beam.vendor.grpc.v1p13p1.io.grpc.ForwardingServerCallListener.onHalfClose(ForwardingServerCallListener.java:23) at org.apache.beam.vendor.grpc.v1p13p1.io.grpc.ForwardingServerCallListener$SimpleForwardingServerCallListener.onHalfClose(ForwardingServerCallListener.java:40) at org.apache.beam.vendor.grpc.v1p13p1.io.grpc.Contexts$ContextualizedServerCallListener.onHalfClose(Contexts.java:86) at org.apache.beam.vendor.grpc.v1p13p1.io.grpc.internal.ServerCallImpl$ServerStreamListenerImpl.halfClosed(ServerCallImpl.java:283) at org.apache.beam.vendor.grpc.v1p13p1.io.grpc.internal.ServerImpl$JumpToApplicationThreadServerStreamListener$1HalfClosed.runInContext(ServerImpl.java:707) at org.apache.beam.vendor.grpc.v1p13p1.io.grpc.internal.ContextRunnable.run(ContextRunnable.java:37) at org.apache.beam.vendor.grpc.v1p13p1.io.grpc.internal.SerializingExecutor.run(SerializingExecutor.java:123) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748) On 27 May 2019, at 6:53 PM, Maximilian Michels <[email protected]<mailto:[email protected]>> wrote: Hi Mingliang, The environment is created for each TaskManager. For docker, will it create one docker per flink taskmanager? Yes. For process, does it mean start a python process to run the user code? And it seems "command" should be set in the environment config, but what should it be? You will have to start the same Python SDK Harness which would run inside a Docker container if you had chosen Docker. This is a more manual approach which should only be chosen if you cannot use Docker. For external(loopback), does it mean let flink operator to call an external service and by default set to the place where I submit the beam job? This looks like all the data will be shift to a single machine and processed there. This intended for a long-running SDK Harness which is already running when you run your pipeline. Thus, you only provide the address to the already running SDK Harness. Cheers, Max On 26.05.19 13:51, 青雉（祁明良） wrote: Hi All, I'm currently trying python portable runner with Flink. I see there are 3 kinds of environment_type available "docker/process/external(loopback)" when submit a job. But I didn't find any material explain more. 1.
