Yun Tang commented on FLINK-23515:
----------------------------------

[~soberChina0@gamil.com] This is a bug as it attempts to modify configuration get fro. task runtime info. You have to set it in the flink-conf.yaml to work around it currently.
BTW, why do you close this and which ticket is duplicated with this one?
