--------------------------------
Summary: The impact of cpu cores on test results for
StreamingJobGraphGeneratorTest#testSlotSharingResourceConfigurationWithDefaultSlotSharingGroup
Key: FLINK-23425
URL: https://issues.apache.org/jira/browse/FLINK-23425
Project: Flink
Issue Type: Bug
Components: Tests
Reporter: tartarus
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.
