yes it is required, as otherwise it gives error "Exception in thread "main" java.lang.IllegalArgumentException: Unknown 'runner' specified 'DataflowRunner', supported pipeline runners [DirectRunner, PortableRunner, TestUniversalRunner]"

yes. -Pdataflow-runner is a flag for maven pprofile. It adds beam-runners-google-cloud-dataflow-java to classpath; --runner=DayaflowRinner is a pipeline option.
