> Key: FLINK-8270
> URL: https://issues.apache.org/jira/browse/FLINK-8270
> Project: Flink
> Issue Type: Bug
> Components: Security
> Affects Versions: 1.4.0
> Reporter: Tzu-Li (Gordon) Tai
> Priority: Blocker
> Fix For: 1.5.0, 1.4.1

> This is a "recurrence" of FLINK-5580. The TMs in Yarn deployment modes are
> again not using the correct local paths for shipped Keytab files.
> The cause was accidental due to this change:
> https://github.com/apache/flink/commit/7f1c23317453859ce3b136b6e13f698d3fee34a1#diff-a81afdf5ce0872836ac6fadb603d483e.
> Things to consider:
> 1) The above accidental breaking change was actually targeting a minor
> refactor on the "integration test scenario" code block in
> {{YarnTaskManagerRunner}}. It would be best if we can remove that test case
> code block from the main code.
> 2) Unit test coverage is apparently not enough. As this incidence shows, any
> slight changes can cause this issue to easily resurface again.
