### What changes were proposed in this pull request? This PR updates the Java 17 support description in `docs/running-on-yarn.md` to reflect Apache Hadoop 3.5.0, which Spark upgraded to in SPARK-55657. Before: > Apache Hadoop does not support Java 17 as of 3.4.1, while Apache Spark requires at least Java 17 since 4.0.0, so a different JDK should be configured for Spark applications. After: > Apache Hadoop supports Java 17 since 3.5.0, while Apache Spark requires at least Java 17 since 4.0.0. When running on a YARN cluster whose Hadoop version is older than 3.5.0, a different JDK should be configured for Spark applications. ### Why are the changes needed? Since Apache Hadoop 3.5.0 requires Java 17 (and also works with Java 21 and 25), the statement "Apache Hadoop does not support Java 17 as of 3.4.1" is outdated. Configuring a different JDK is now only needed for YARN clusters running Hadoop versions older than 3.5.0, so the guidance is scoped accordingly while keeping the pointer to the `Configuring different JDKs for Spark Applications` section for users on older clusters. ### Does this PR introduce _any_ user-facing change? No. This is a documentation-only change. ### How was this patch tested? Manual review of the rendered Markdown. ### Was this patch authored or co-authored using generative AI tooling?
