Github user yjhyjhyjh0 commented on the issue: https://github.com/apache/nifi/pull/2166 I've solved this issue by re-cache column type if needed and pass local unit and instance test. The root cause of this issue is that originally disign didn't recognize that column type cache will be clean after instance reboot. This cause later unable to find column type cache with existing state value and throw unhandle IllegalArgumentException. Now if state value exist without corresponding column type cache, we will fetch and cache it.
