[jira] [Comment Edited] (FLINK-14875) Blink planner should pass the
right ExecutionConfig to the creation of serializer
[ https://issues.apache.org/jira/browse/FLINK-14875?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17011347#comment-17011347 ]

--------------------------------------------------------------
How much effort needed for passing the right ExecutionConfig to the creation of serializer? A clean fix should be huge. I don't think we can fix it in 1.10. And we have not exposed ExecutionConfig api to new TableEnvironment. (Only worked in StreamTableEnv)
One solution is using user define TypeInfo: [https://ci.apache.org/projects/flink/flink-docs-master/dev/types_serialization.html#defining-type-information-using-a-factory]

> I find similar problems in [How to set Unmodifiable collection serializer of Kryo in Spark code|https://stackoverflow.com/questions/46818293/how-to-set-unmodifiable-collection-serializer-of-kryo-in-spark-code], is there any way to set unmodifiable collection serializer of Kryo in at present?
