需要去 job-manager/logs中看详细信息：

无法在检查点协调器端创建检查点存储

... 1 more怎么还没有办法创建呢？？？？
看一下我的StateBackend 文件地址是哪里？
看看我的代码
上传的jar 包位置在哪里啊？
查看这里：/job-manager/config
那我就去这个目录下面看看去：
目录地址：/tmp/flink-web-4db3951f-2d85-4732-9a36-2f45c31105fe/flink-web-upload
在这个目录下面我没有办法创建 。
那我换个目录试试：
换了地址以后提交作业成功了。OKOKOKOK，哈哈哈哈哈哈哈哈哈哈哈哈！！！
那我为什么在 /tmp 这里不能创建呢？？？？？？
你猜你猜你猜你猜你猜你猜你猜你猜你猜你猜你猜你猜你猜你猜你猜你猜你猜你猜
抽空再写原因，哈哈哈哈
