---------------------------------------
nvm... just simple excludes. Harmless. Backported to 2.4.

> Key: HBASE-25908
> URL: https://issues.apache.org/jira/browse/HBASE-25908
> Project: HBase
> Issue Type: Improvement
> Components: hadoop3, shading
> Affects Versions: 2.3.0
> Reporter: Wei-Chiu Chuang
> Assignee: Wei-Chiu Chuang
> Priority: Major
> Fix For: 3.0.0-alpha-1, 2.5.0
>
>
> Hadoop 3.3.1 replaced its dependency of javax.activation 1.2.0 with
> jakarta.activation 1.2.1.
> They are essentially the same thing (they even have the same classpath name),
> but Eclipse took over JavaEE development and therefore changed group/artifact
> id.
> (https://stackoverflow.com/questions/46493613/what-is-the-replacement-for-javax-activation-package-in-java-9)
> See HADOOP-17049 for more details. Hadoop 3.3.0 updated jackson-databind to
> 2.10 which shades jakarta.activation, causing classpath conflict.
> The solution to this issue will be similar to HBASE-22268
