Kenneth Knowles updated BEAM-10222:
-----------------------------------
Component/s: (was: sdk-java-core)
runner-dataflow
> Java11 only detects 1 CPU when running on Dataflow
> --------------------------------------------------
>
> Key: BEAM-10222
> URL: https://issues.apache.org/jira/browse/BEAM-10222
> Project: Beam
> Issue Type: Bug
> Components: runner-dataflow
> Reporter: Mikhail Gryzykhin
> Priority: P2
>
> When specifying the worker-type as "n1-highcpu-4" the resulting thread number is 4 when the pipeline is compiled by Java8, and only 1 when the pipeline is compiled by Java11.
> Specifying numberOfWorkerHarnessThreads does not change amount of detected threads.
> Amount of available CPUs is received via "Runtime.getRuntime().availableProcessors()"
