uros-b opened a new pull request, #57930: URL: https://github.com/apache/spark/pull/57930
### What changes were proposed in this pull request? Fixes four usage strings that disagree with the code around them: - `DirectKafkaWordCount` and `DirectKerberizedKafkaWordCount`: the class comment gains the missing `<groupId>` argument - `SkewedGroupByTest`: `Usage: GroupByTest` becomes `Usage: SkewedGroupByTest` - `JavaRecoverableNetworkWordCount`: `You arguments were` becomes `Your arguments were` ### Why are the changes needed? Each defect is contradicted by its own file: - Both Kafka examples gate on `args.length < 3`, destructure `val Array(brokers, groupId, topics) = args`, already print the three-argument form at runtime, and already describe `<groupId>` on the line below the usage string. SPARK-27973 corrected the runtime message for the first example but left the comment out of sync. The Java twins (`JavaDirectKafkaWordCount`, `JavaDirectKerberizedKafkaWordCount`) are already correct, so this closes the gap. - `SkewedGroupByTest`'s comment names `GroupByTest`, which is a different example that also exists, so copying the line runs the wrong job. The sibling `SimpleSkewedGroupByTest` self-names correctly. - The Scala counterpart `RecoverableNetworkWordCount` already reads `Your arguments were`, so the fix aligns the twins. ### Does this PR introduce _any_ user-facing change? No, other than the corrected example text. ### How was this patch tested? Comment and message text only. Each correction was cross-checked against the example's own argument gate, destructuring, and runtime message. A sweep of every Scala and Java example for a mismatch between the comment's `Usage:` class name and the enclosing object name found only the `SkewedGroupByTest` case fixed here. ### Was this patch authored or co-authored using generative AI tooling?
