> [StateAssignmentOperation.checkStateMappingCompleteness|https://github.com/apache/flink/blob/master/flink-runtime/src/main/java/org/apache/flink/runtime/checkpoint/StateAssignmentOperation.java#L555] doesn't check for UserDefinedOperatorIDs (specified using setUidHash), causing the exception:
> {code}
> java.lang.IllegalStateException: There is no operator for the state {}
> {code}
> to be thrown when a savepoint can't be mapped to an ExecutionJobVertex, even when the operator hash is explicitly specified.
> I believe this logic should be extended to also include UserDefinedOperatorIDs as so:
> {code:java}
> for (ExecutionJobVertex executionJobVertex : tasks) {
> allOperatorIDs.addAll(executionJobVertex.getOperatorIDs());
> allOperatorIDs.addAll(executionJobVertex.getUserDefinedOperatorIDs());
> }
> {code}
