Kevin Risden commented on SOLR-15355:
-------------------------------------

There are a bunch of changes between 3.2.0 and 3.2.2:

https://github.com/apache/hadoop/compare/rel/release-3.2.0...rel/release-3.2.2#diff-df2aa66a3757d73c93849b3a279d42a4634b0aed3550cdd2ead32d2fa06bf49eR176

The AWS Java SDK version definitely changed:

{code:java}
- <aws-java-sdk.version>1.11.375</aws-java-sdk.version>
+ <aws-java-sdk.version>1.11.563</aws-java-sdk.version>
{code}

I'm not sure if Solr uses the shaded Hadoop client libraries for cloud access 
or ends up having to declare the AWS Java SDK version in use as well.
