[jira] [Commented] (FLINK-19065) java.lang.IllegalStateException: Auto generated UIDs have been disabled on join

Aljoscha Krettek commented on FLINK-19065:
------------------------------------------

Could you quickly try and run that on a cluster without {{disableAutoGeneratedUIDs()}}? There's a {{map()}} used internally somewhere but I can't find it off the top of my head right now.
