Juntao Hu updated FLINK-35302:
------------------------------
Description:
As
[FLIP-401|https://cwiki.apache.org/confluence/display/FLINK/FLIP-401%3A+REST+API+JSON+response+deserialization+unknown+field+tolerance]
and FLINK-33258 mentioned, when an old version REST client receives response
from a new version REST server, with strict JSON mapper, the client will throw
exceptions on newly added fields, which is not convenient for situations where
a centralized client deals with REST servers of different versions (e.g. k8s
operator).
But this incompatibility can also happens at server side, when a new version
REST client sends requests to an old version REST server with additional
fields. Making server flexible with unknown fields can save clients from
backward compatibility code.
