Biao Geng edited comment on FLINK-26216 at 2/21/22, 2:55 AM: ------------------------------------------------------------- [~ConradJam] Thanks for you reply! You give a very valuable point and in my opinion, such straightforward config error should be raised in front instead of in reconcile phase, just like the target of this https://issues.apache.org/jira/browse/FLINK-26136 . I will try to finish my refactor PR with the simple fix of JM HA ASAP and for the validation part, I think you can either try to take FLINK-26136 or submit a following PR for this ticket only. I believe both choice will be encouraged by our community. was (Author: bgeng777): [~ConradJam] You give a very valuable point and in my opinion, such straightforward config error should be raised in front instead of in reconcile phase, just like the target of this https://issues.apache.org/jira/browse/FLINK-26136 .
