[HyukjinKwon]

will we have a branch here?

[Yikun]

No, I think only maintain a master branch with all release dockerfiles is enough.

So, only branch == "master" is valid in here, I can remove the fix_version_from_branch I think

And we should also remove L571:

    pick_prompt = "Would you like to pick %s into another branch?" % merge_hash
    while input("\n%s (y/n): " % pick_prompt).lower() == "y":
        merged_refs = merged_refs + [cherry_pick(pr_num, merge_hash, latest_branch)]

[HyukjinKwon]

If this script is almost same as Apache Spark's repo, let's just keep them as are.
If the diff is already large, we could remove these codes out.

[Yikun]

Yes, it's almost same diff is here: e4107a7. So just let me remove L571 is enough (to remove redundant backport process):

    pick_prompt = "Would you like to pick %s into another branch?" % merge_hash
    while input("\n%s (y/n): " % pick_prompt).lower() == "y":
        merged_refs = merged_refs + [cherry_pick(pr_num, merge_hash, latest_branch)]
