Summary: StateQueryResult#getOnlyPartitionResult should not throw for FailedQueryResult Key: KAFKA-15768 URL: https://issues.apache.org/jira/browse/KAFKA-15768 Project: Kafka Issue Type: Bug Components: streams Reporter: Matthias J. Sax Calling `StateQueryResult#getOnlyPartitionResult` crashes with an incorrect `IllegalArgumentException` if the only result is a `FailedQueryResult`. The issue is the internal `filter(r -> r.getResult() != 0)` step, that blindly (and incorrectly) calls `getResult`. Given the semantics of `getOnlyPartitionResult` we should not care if the result is SuccessQueryResult or FailedQueryResult, but only check if there is a single result or not. (The user has not means to avoid getting an exception otherwise.) Side-note: why does `FailedQueryResult#getResult` throw an IllegalArgumentException (there is no argument passed into the method – it should rather be an `IllegalStateException` – but I guess we would need a KIP for this fix?) -- This message was sent by Atlassian Jira (v8.20.10#820010)
