Hi, @jbalchan can you take a look at the ci failure?

[xuyangzhong]

@jbalchan You only removed the method TableDescriptor#forManaged without adapting all the code that uses that method.

[xuyangzhong]

Since the removal work for managed table is too big, I have created a new pr https://github.com/apache/flink/pull/25910 for that and add you as a co-author there.

Thankyou @xuyangzhong. Closing this PR since this is no longer useful.
