             Summary: Add batch E2E test which runs with fewer slots than parallelism
                 Key: FLINK-13441
                 URL: https://issues.apache.org/jira/browse/FLINK-13441
             Project: Flink
          Issue Type: Test
          Components: API / DataSet, Tests
            Reporter: Till Rohrmann
             Fix For: 1.9.0


We should adapt the existing batch E2E test to use the newly introduced {{ScheduleMode#LAZY_FROM_SOURCES_WITH_BATCH_SLOT_REQUEST}} and verify that the job runs on a cluster with fewer slots than the job's parallelism. In order to make this work, we need to set the shuffles to be blocking via {{ExecutionMode#BATCH}}. As a batch job we should use the {{DataSetAllroundTestProgram}}.
