-----------------------------------------------
> Add automated tests for Impala Helm chart configuration defaults
> ----------------------------------------------------------------

> Key: IMPALA-15028
> URL: https://issues.apache.org/jira/browse/IMPALA-15028
> Project: IMPALA
> Issue Type: Task
> Reporter: Anubhav Jindal
> Assignee: Anubhav Jindal
> Priority: Major
>
> *Problem*
> The new Impala Helm chart currently relies on manual validation for several
> key behaviors (for example image defaults, port exposure, and config-driven
> daemon flags). We need automated coverage to prevent regressions and to make
> review/verification repeatable.
> *Proposed Change*
> Add automated tests for the Helm chart that validate rendered manifests and
> key runtime-oriented configuration behavior.
> Initial coverage should include:
> * Default image prefix renders {{apache/impala:4.5.0-...}} component images.
> * Deprecated Beeswax port is not exposed in {{impalad}} deployment/service.
> * {{{}catalogd.v{}}}, {{{}impalad.v{}}}, and {{statestored.v}} values
> correctly render daemon {{-v}} args (default {{{}1{}}}, overrideable).
> * {{catalogd.hmsEventPollingIntervalS}} is rendered correctly, including
> compatibility value {{{}0{}}}.
> * {{hms.securityContext}} values (e.g. {{{}runAsUser{}}},
> {{{}runAsGroup{}}}) render correctly when set.
> * Chart lint/template checks are exercised in CI-friendly scripts.
> Implementation can use a lightweight chart test framework (or script-based
> golden checks) that runs with {{helm lint}} + {{helm template}} assertions.
> *Testing*
> * Add automated test cases for default and override values.
> * Verify tests fail on intentional regressions (e.g., reintroducing Beeswax
> port).
> * Run tests in local/dev CI environment and include invocation steps in docs.
> *Compatibility / Risk*
> Low risk. This change adds test coverage only and does not alter runtime
> behavior of existing chart defaults.
