Hi all, Although Hadoop 2 is alive (version 2.10.2 was released on 31 May 2022 with "211 bug fixes, improvements and enhancements since 2.10.1" [1]), versions 2.9.x and older are EOL, as are version 3.0.x and 3.1.x [2].
On Java support: Hadoop 2.10 supports both Java 7 & Java 8. Hadoop 3.3 and later support both Java 8 & Java 11 [3]. This confirms what Steve pointed out: Hadoop 2 does not support Java >8. Now Java 8 has reached EOL a few months ago (on 31 March 2022), though it'll receive security updates until 31 March 2025 [4]. This proves Hadoop 2 is a dead end, and fully obsolete in 2 years, 9 months. As a result, I'd be happy to drop support for Hadoop 2 from Avro in the next major release.
