问题1

Flink Application Mode模式执行任务时出错

 The program finished with the following exception:

java.lang.IllegalStateException: No ClusterClientFactory found. If you were targeting a Yarn cluster, please make sure to export the HADOOP_CLASSPATH environment variable or have hadoop in your classpath. For more information refer to the "Deployment" section of the official Apache Flink documentation.

问题1原因：

bin/flink run-application -t yarn-appliction -c com.atguigu.flink.chapter01.Flink02_UnBounded_WC_Lambda ./flink211125-1.0-SNAPSHOT.jar

执行上述命令时，手打打少了一个a，导致奇怪的错误。
正确命令如下：
bin/flink run-application -t yarn-application -c com.atguigu.flink.chapter01.Flink02_UnBounded_WC_Lambda ./flink211125-1.0-SNAPSHOT.jar

问题2

配置了flink-yarn高可用后，提交任务测试。

bin/flink run-application -t yarn-application -c com.atguigu.flink.chapter01.Flink02_UnBounded_WC_Lambda ./flink211125-1.0-SNAPSHOT.jar

之后一直处于 ACCEPTED 状态。

Deploying cluster, current state ACCEPTED
Deployment took more than 60 seconds. Please check if the requested resources are available in the YARN cluster

问题2原因

配置了高可用以后要起zookeeper, 否则一直连不上zookeeper，会一直是ACCEPTED状态，超过60秒还会提示你检查yarn集群资源够不够。

原因就是：配了高可用但没有起zookeeper，把zookeeper起了之后问题解决。
