@aajisaka , thank you for the patch. Can you also please update the release script? It has some logic that assumes the old file names:

https://github.com/apache/hadoop/blob/trunk/dev-support/bin/create-release#L204-L210

Can you also please look at pre-submit? I think we have been having some infra problems, but this failure looks different from the other potential infra problems I've seen.

[aajisaka]

Updated the release script and Jenkinsfile. Let's see the CI is fixed or not.

I guess the mvnsite failures in pre-submit are waiting on your other changes in #8182 ?

Thank you @aajisaka !
