1. 异常详情

Exception in thread "main" java.lang.IllegalStateException: No operators defined in streaming topology. Cannot generate StreamGraph.
	at org.apache.flink.table.planner.utils.ExecutorUtils.generateStreamGraph(ExecutorUtils.java:47)

	at org.apache.flink.table.api.internal.TableEnvironmentImpl.execute(TableEnvironmentImpl.java:1197)

2. 报错代码（基于flink1.11版本）

EnvironmentSettings tableEnvSettings = EnvironmentSettings
            .newInstance()
            .useBlinkPlanner()
            .inBatchMode()
            .build</
