Martijn Visser updated FLINK-41378:
-----------------------------------
Fix Version/s: 2.5.0
> Raise the minimum supported Hadoop version to 3.4.3
> ---------------------------------------------------
>
> Key: FLINK-41378
> URL: https://issues.apache.org/jira/browse/FLINK-41378
> Project: Flink
> Issue Type: Technical Debt
> Components: FileSystems
> Reporter: Martijn Visser
> Assignee: Martijn Visser
> Priority: Major
> Fix For: 2.5.0
>
>
> Flink compiles and tests against Hadoop 2.10.2, but on Java 23 and later
> Hadoop before 3.4.3 fails with getSubject is not supported (HADOOP-19212).
> That is why FLINK-40603 already builds the Java 25 profile against 3.4.3.
> Hadoop 3.4.3 also runs on Java 11, so we can use it for every Java version
> and drop Hadoop 2.
> This sets flink.hadoop.version to 3.4.3 and removes the Java 25 override. It
> also moves the CI stages that pass -Dflink.hadoop.version=2.10.2 to the
> default, folds the hadoop3-tests profiles into the default build, moves the
> YARN e2e test cluster to Hadoop 3 and updates the docs.
