Flink任务报：Could not allocate the required slot within slot request timeout._你的代码有

问题描述

问题描述：Flink job提交到集群上跑，提交成功了，但是每次都是等很久之后就失败了，一直报：Could not allocate the required slot within slot request timeout. Please make sure that the cluster has enough resources.

此外，跑了Spark任务和Flink官方的批处理的WordCount例子都是可以跑成功的；

首先检查是否集群资源不够的问题，然后再检查是否是打包的问题；

我这边出现错误的原因是因为我的POM配置文件配置有误；

POM文件有问题，漏写了几个<scope>provided</scope>，导致有些Flink相关的包也给打包进去了；

解决办法

将漏写的?<scope>provided</scope> 补上，重新打包运行；
