1 Retrying connect to server
Flink on yarn 依赖 hadoop 集群，在没有启动hadoop之前，直接执行Flink启动命令
./bin/yarn-session.sh -n 1 -jm 1024 -tm 4096
结果就是flink连不上ResourceManager，脚本一直卡在着进行重试

所以，先别着急，启动好 hadoop 环境后再启动Flink。
2 Unable to get ClusterClient status from Application Client
hadoop 已经启动了，这下执行 Flink 启动命令
./bin/yarn-session.sh -n 1 -jm 1024 -tm 4096
Flink 还是没有启动成功

这种错误一般是 hadoop 集群资源（内存、磁盘、虚拟内存等等）不足造成的。
并且多数情况是由于分配的虚拟内存超出限制，两种方法解决：
（1）将 hadoop 的检查虚拟内存关闭掉。如下：
<property>
<name>yarn.nodemanager.vmem-check-enabled</name>
<value>false</value>
</property>
（2）把分配的内存调小，尝试改为 800 即可正常启动。这种方法不是很长久，运行一段时间，最终container还是会被kill掉。

查了下，大部分都认为是commons-collections包冲突引起，flink用的版本比较老（3.2.2），自己有可能引入高版本的，但自己jar里面根本就没有引用。一直没有头绪。
后来，发现flink老是因为资源不足挂掉，考虑是不是因为资源不足，导致flink没有启动完成导致的。
加大flink的启动资源参数后，重新提交jar，完美运行。
