MiniClusterJobClient

public MiniClusterJobClient(org.apache.flink.api.common.JobID jobID,
                            MiniCluster miniCluster,
                            ClassLoader classLoader,
                            MiniClusterJobClient.JobFinalizationBehavior finalizationBehaviour)

Creates a MiniClusterJobClient for the given JobID and MiniCluster. This will shut down the MiniCluster after job result retrieval if shutdownCluster is true.
