One use case that can contribute to this error message is using LEFT ANTI JOIN. The problem is that Okera does not support "left anti join" at this point. To workaround this issue is to mark this as an external view so Hive can evaluate the join. You can find more information on external views at https://okera.zendesk.com/hc/en-us/articles/360005811214
