There was a problem hiding this comment.
Are the hadoop-2 profiles in java-exec and storage-phoenix already taken care of? I don't see them removed here.

DRILL-8533: Remove Hadoop 2 Support
Description
This PR removes Drill's unofficial support for Hadoop 2. Previously, you could build Drill with a profile to support Hadoop 2, however, due to numerous CVEs in Hadoop 2 and the lack of ongoing support, we have decided to remove that support.
This PR effectively removes the work done one DRILL-8107 and ends Drill's support for Hadoop 2.
Documentation
I updated the developer docs, but there really are no user-facing changes other than ending the support for Hadoop 2.
Testing
Ran existing unit tests.
