local模式成功,YARN模式下执行wordcount失败,求解

[wzwdev1980]

部署HDFS和YARN集群，hdfs和YARN自动切换均成功，HDFS上传文件成功，通过本地分布式计算也成功，在yarn模式下执行失败

节点配置如下：


NodeManager报的警告：

2018-04-27 05:16:37,791 WARN org.apache.hadoop.yarn.server.nodemanager.containermanager.ContainerManagerImpl: couldn't find app application_1530182275331_0001 while processing FINISH_CONTAINERS event



YARN执行时控制台显示的：

1.检查一下yarn-site.xml是否加到工程conf下
2.贴一下你的执行命令，看是否指定--master yarn-client/cluster

不行，还是错：

请问这个问题解决了吗，我刚好也是遇到这个问题，动态添加yarn nodemanager,任务调度不过来
