-----------------------------

             Summary: Harden Tests when availableProcessors is 1
                 Key: FLINK-12800
                 URL: https://issues.apache.org/jira/browse/FLINK-12800
             Project: Flink
          Issue Type: Bug
          Components: Tests
    Affects Versions: 1.8.0
            Reporter: leesf
            Assignee: leesf
             Fix For: 1.9.0


Some tests failed when Runtime.getRuntime().availableProcessors() is 1. The source vertex and other vertex may chained, thus make test failed. such as 

AsyncWaitOperatorTest#testOperatorChainWithProcessingTime

StreamingJobGraphGeneratorTest#testChainStartEndSetting

StreamOperatorChainingTest#testMultiChainingWithObjectReuse

StreamOperatorChainingTest#testMultiChainingWithoutObjectReuse

 

So we would specify parallelism of vertex directly to let its not chained with source .
