GJL commented on issue #6491: [FLINK-10057] Update FlinkYarnSessionCli.java URL: https://github.com/apache/flink/pull/6491#issuecomment-430941464 Merging because all comments from @StefanRRichter have been addressed. Here are some additional remarks: * `isYarnPropertiesFileMode` is not in the performance critical path, and there are not many options to be processed. Therefore, the method should be optimized for readability. * Your changes improve readability but we could do better by extracting the logic in the loop, e.g.,: ``` private boolean isYarnPropertiesFileMode(CommandLine commandLine) { final boolean isNotAddressOptionSet = !commandLine.hasOption(addressOption.getOpt()); return isNotAddressOptionSet && isNotYarnOptionsSet(commandLine); } ``` * Please respect the commit [message guidelines](https://flink.apache.org/contribute-code.html#coding-guidelines): > Commit message. A pull request must relate to a Jira issue; create an issue if none exists for the change you want to make. The latest commit message should reference that issue. An example commit message would be [FLINK-633] Fix NullPointerException for empty UDF parameters. That way, the pull request automatically gives a description of what it does, for example, what bug does it fix in what way.
