------------------------------------------
Summary: Flink checkStateMappingCompleteness doesn't include
UserDefinedOperatorIDs
Key: FLINK-16638
URL: https://issues.apache.org/jira/browse/FLINK-16638
Project: Flink
Issue Type: Bug
Components: Runtime / Checkpointing
Affects Versions: 1.10.0
Reporter: Bashar Abdul Jawad
[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}
