vdiravka commented on issue #1404: DRILL-6639: Exception happens while displaying operator profiles for … URL: https://github.com/apache/drill/pull/1404#issuecomment-408372180 @arina-ielchiieva The operator type was always (in earlier Drill versions) null, if operator doesn't exist in protobuf file. But DRILL-6279 (`OperatorWrapper.getSpillCycleMetricIndex()`) enabled using of `operatorType` without handling `null` cases. It is possible to handle everywhere such null cases. But the proper way is to update to the latest protobuf (3.6.0 for now) version, which allows to set `UNRECOGNIZED` Enum NullValue. If it is fine I will proceed with a new Jira ticket.
