[jira] [Updated] (FLINK-33268) Flink REST API response parsing should support backward compatible changes like new fields

     [ https://issues.apache.org/jira/browse/FLINK-33268?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Gabor Somogyi updated FLINK-33268:
----------------------------------
    Description: 
At the moment Flink is not ignoring unknown fields when parsing REST responses. An example for such a class is JobDetailsInfo but this applies to all others. It would be good to add this support to increase compatibility.

The real life use-case is when the operator wants to handle 2 jobs with 2 different Flink versions where the newer version has added a new field to any REST response. Such case the operator gets an exception when tries to poll the job details with the additional field.
