##修改hdfs日志的读写权限
hdfs dfs -ls /tmp/logs/autoflow/logs
hdfs dfs -chmod a+rwx /tmp/logs/autoflow/logs

##查看所有node节点状态
yarn node -list -all

##查看当前运行的应用
yarn application -list

##杀掉application
yarn application -kill application_1703647286630_204559

##获取application日志
##yarn logs -applicationId
yarn logs -applicationId application_1703647286630_204559

##获取container日志
##yarn logs -applicationId -containerId
yarn logs -applicationId application_1678411202227_0001 -containerId container_1678411202227_0001_01_000001 > file.txt

##列出所有尝试的applicationattempt
##yarn applicationattempt -list
yarn applicationattempt -list application_1703647286630_204559

##列出所有Container（容器在任务完成之后就销毁了）
##yarn container -list
yarn container -list appattempt_1703647286630_204559_000001

补充命令：

##获取文件前1万行
head -n 10000 file.txt > newfile.txt

##获取文件最后1万行
tail -n 10000 file.txt > newfile.txt

##查看报错信息
