Yes, this feature was indeed removed, and has been since 1.9.0.
See https://lists.apache.org/thread/oby7fmz9crphonxw3l0g8b9zvybg3sno for
some background.

Greetings all,
I am trying to test the rescaling feature of Flink 1.14, however when
i send a rest request to the endpoint I receive the following message:
"org.apache.flink.runtime.rest.handler.RestHandlerException: Rescaling
is temporarily disabled. See FLINK-12312.

The only information i can get on this is for 1.9
(https://issues.apache.org/jira/browse/FLINK-12312
<https://issues.apache.org/jira/browse/FLINK-12312>)
Can we confirm that this feature is disabled?

Morgan.
