URL: https://github.com/apache/hadoop/pull/8653#issuecomment-5370475919
> Could we use LLM to search the codebase and list all components that might
need to be migrated?
>
> As you know, we went through a painful Jersey 1.x => 2.x upgrade process,
and even now, we're still receiving some issues caused by the Jersey upgrade.
This means that the current branch-3.5 is unstable (branch-3.5 has only
released one version, 3.5.0), and we're still far from 3.6.0. Merging this
change now might not be a good time (meaning the 3.5 backport could have a lot
of conflicts).
>
> This change will be a breaking change for all downstream projects of
Hadoop (perhaps Spark is an exception because it uses the Hadoop Shaded
Client). We may need to initiate a cross-project discussion on the mailing list
and try to reach a consensus before moving forward.
I can help with the LLM part. Using Claude, I asked for a script to scan the
codebase and an analysis of the migration viability. Please have a look at the
attached analysis document.

> Project: Hadoop Common
> Issue Type: Task
> Reporter: PJ Fanning
> Priority: Major
> Labels: pull-request-available
>
> See HADOOP-19910 - there is a CVE in Jetty but releases of 9.4 are rare and
> are 'sponsored' - Jetty 9.4 is not actively maintained. There are some
> commercial forks.
> Jetty 12 needs Java 17+.
> Will also force Jersey to upgraded to 3 or 4.
> And to replace many javax classes/jars with their jakarta equivalents.
