Dongjoon Hyun commented on SPARK-28938:
---------------------------------------

[~AceHack]. Thank you for filing the JIRA. Yes. We had better upgrade it. However, the image is still there, isn't it? Is it removed from Docker registry? As long as the old image exists there, I believe this issue is a `Minor` improvement .
