Description

https://github.com/apache/beam/blob/master/runners/google-cloud-dataflow-java/worker/src/test/java/org/apache/beam/runners/dataflow/worker/fn/BeamFnControlServiceTest.java

Tests for BeamFnControlService are currently flaky. The test attempts to verify that onCompleted was called on the mock streams, but that function gets called on a separate thread, so occasionally the function will not have been called yet, despite the server being shut down.
