原因：
主要原因在于flink自1.8之后不再提供对应的hadoop编译版本，需要用户自己重新编译或者提供一个flink和hadoop连接器。
解决方法：
这里提供的是flink-shaded-hadoop-2-uber-2.7.5-9.0.jar，可以到[maven](Central Repository: org/apache/flink/flink-shaded-hadoop-2-uber/2.7.5-9.0 (maven.org)
)中央仓库下载。将该jar拷贝到flink目录的lib下，同步到每一台flink机器即可。然后重启flink。
进程查看

出现了StandaloneSessionClusterEntrypoint进程
再次运行jar执行正常：
