lamber-ken opened a new pull request #7279: [hotfix] add hadoop user name to yarn logs command
URL: https://github.com/apache/flink/pull/7279
 
 
   ## What is the purpose of the change
   
   if use yarn proxy user to submit the application to yarn cluser, the real hadoop user name will be the proxy user name, so use `yarn logs -applicationId <appId>`  will return nothing. it's right to use `yarn logs -applicationId <appId> -appOwner <userName>`.
   
   example, before submiting app to yarn cluster, if set the proxy user, when the app finished or killed.
   `yarn logs -applicationId <appId>` will return nothing.
   `yarn logs -applicationId <appId> -appOwner test` will return log info.
   
   #### proxy user
   ```
   export HADOOP_USER_NAME=flink
   export HADOOP_PROXY_USER=test
   ```
