【yarn】Yarn 报错 Application submission is not finished, submitted application xxxxxxx

提交yarn任务时，始终无法将任务提交到yarn上，并一直在打印日志：

打印的日志如下：

21/10/06 02:43:24 INFO impl.YarnClientImpl: Application submission is not finished, submitted application application_1633458210016_0364 is still in SUBMITTED
21/10/06 02:43:26 INFO impl.YarnClientImpl: Application submission is not finished, submitted application application_1633458210016_0364 is still in SUBMITTED
21/10/06 02:43:28 INFO impl.YarnClientImpl: Application submission is not finished, submitted application application_1633458210016_0364 is still in SUBMITTED
21/10/06 02:43:30 INFO impl.YarnClientImpl: Application submission is not finished, submitted application application_1633458210016_0364 is still in SUBMITTED

造成该问题的原因可能有：

1. yarn提交的任务过多，处理不过来。
2. resource manager向 ZooKeeper 写入太多数据并达到缓冲区限制。

我们可以通过查看yarn资源池使用情况来查看队列待定的容器数量，如果数量明显过多，将问题任务kill掉。

将问题任务kill掉。

问题任务：

yarn application -kill application_id

此时可能会遇到任务无法kill掉的情况，需要将active resoucemanager 停止，然后重新kill 任务。

增加 ZooKeeper 缓冲区限制。

此方法没有进行测试，有兴趣的同学可以测试一下。
