Description

By default, LocalStreamEnvironment will use the number of cpu cores(Runtime.getRuntime().availableProcessors()) as the default parallelism;

In our company, we will use a 1-core docker container to run the test.

Then StreamingJobGraphGeneratorTest#testSlotSharingResourceConfigurationWithDefaultSlotSharingGroup failed.

because the parallelism of map operator is 1, so the number of Vertex is 1, not expected 2 anymore.
