引用: 原因:socket连接重置,可能是使用不同的方式或者是重复提交flink任务,导致socket端口占用导致。2.No new data sinks have been defined since。原因:未被定义的数据输出 flink的批处理不需要行动算子来触发,因此删除最后一行的 //启动流式处理,如果没有该行代码上面的程序不会运行 streamEnv.execute("wordcount")。
"Exception in thread "main" org.apache.flink.runtime.client.JobExecutionException: Job execution failed." 这个错误是由于flink作业执行失败所引发的异常。可能的原因是网络连接重置或未定义的数据输出。对于网络连接重置,可以检查是否使用了不同的连接方式或是否重复提交了flink任务。对于未定义的数据输出,可以检查是否没有定义数据的输出操作。
