This is basically adding a non-production code relevant path in for testing purposes (i.e., it is only ever non-null in the `YarnTaskManagerRunnerTest`). I think it would be better if we have a `protected createMainRunner(...)` method that can be overriden to inject the mock runner dependency for testing. > Flink YARN deployment with Kerberos enabled not working > -------------------------------------------------------- > > Key: FLINK-8275 > URL: https://issues.apache.org/jira/browse/FLINK-8275 > Project: Flink > Issue Type: Bug > Components: Security > Affects Versions: 1.4.0 > Reporter: Shuyi Chen > Assignee: Shuyi Chen > Priority: Blocker > Fix For: 1.5.0, 1.4.1 > > > The local keytab path in YarnTaskManagerRunner is incorrectly set to the > ApplicationMaster's local keytab path.
