zjffdu opened a new pull request #8144: [FLINK-12159]. Enable YarnMiniCluster integration test under non-secure mode
URL: https://github.com/apache/flink/pull/8144
 
 
   ## What is the purpose of the change
   I can not run flink in YarnMiniCluster for integration test because yarn-site.xml is not shipped to yarn container (krb5Config must be non-empty otherwise yarn-site.xml won't been shipped). It doesn't make sense to to only allow yarn integration under secure mode. So this PR just try to enable YarnMiniCluster integration test under non-secure mode. I tested this PR for zeppelin flink integration test.
   
   
   ## Brief change log
   
   Straightforward code refactoring to separate `yarn-site.xml` and `krb5Config` file.
   
   
   ## Verifying this change

   This change is a trivial rework / code cleanup without any test coverage.
   I verified this PR in zeppelin flink integration test.
