…re-attach monitorSparkKubernetesApp() re-resolves the tracked Kubernetes application on every poll cycle via a tag substring match, with no check that the resolved app ID matches what was seen on a previous poll. A stale/leaked tag or a tag substring collision could silently switch which application is tracked. Latch the first observed app ID per session and reject any later poll that observes a different app ID for the same tag, failing the promise and draining the session to FAILED rather than silently continuing.

SparkKubernetesApp.monitorSparkKubernetesApp()re-resolves the tracked Kubernetesapplication on every poll cycle via a tag substring match
(
getApplicationTag.contains(appTag)), and previously used whatever app ID it foundwith no check against what it had seen before. If a stale/leaked tag reappeared or a
tag-substring collision occurred, a later poll could silently start tracking a
different application under the same tag, with no error.
This adds a
knownAppIdlatch: the first observed app ID for a session is remembered,and any later poll that resolves a different app ID for the same tag is rejected —
the promise fails, the session is driven to
FAILED, and the tag is marked leaked,mirroring the treatment of other terminal monitoring failures.
The decision logic is extracted into a pure, testable function,
SparkKubernetesApp.latchAppId(), following the pattern used in #544.How was this patch tested?
Added
latchAppIdunit tests toSparkKubernetesAppSpeccovering: no app ID knownyet (latches), matching app ID re-observed (no-op), and mismatched app ID observed
under the same tag (rejected with a diagnostic message naming the tag and both IDs).
Ran
mvn -pl server -am test -Dtest=SparkKubernetesAppSpec: 14/14 tests pass (3 new).Was this patch authored or co-authored using generative AI tooling?
Yes. Generated-by: Claude Code (Sonnet 5, Anthropic), used to implement the
latchAppIdextraction and its unit tests, under human review. Please refer to the
ASF Generative Tooling Guidance
for details.
