Hi everyone, I want to discuss adding the Hadoop upgrade to the list after moving to Iceberg 2.0. We still compile against Hadoop 2.7.3 to ensure we support as many users as possible. Hadoop 2.7.3 was released August 2016 <https://hadoop.apache.org/release/2.7.3.html> and is not maintained anymore <https://endoflife.date/apache-hadoop> for a long time.
My main reason for doing the upgrade is that on the Parquet MR project, I've been pushing back the Hadoop upgrade to ensure compatibility with Iceberg. However, at some point, we have to pull the trigger here. This will simplify things on the Parquet side and avoid having to check if the Java API Exists and such. Since Hadoop 3.3+ officially supports Java 11 <https://cwiki.apache.org/confluence/display/HADOOP/Hadoop+Java+Versions>, I would suggest dropping everything below that. I wanted to check on the mailing list if there are any thoughts and or concerns. Kind regards, Fokko
