> *Problem*
> The current Impala Helm chart supports LDAP and Ranger-related options, but 
> does not expose OAuth authentication configuration for {{{}impalad{}}}. 
> Review feedback on {{IMPALA-14974}} requested OAuth support since it is 
> commonly used in Kubernetes environments.
> *Proposed Change*
> Add Helm values and template wiring to configure OAuth-related {{impalad}} 
> startup flags in a typed and discoverable way.
> The change should:
>  * Introduce OAuth config keys under {{values.yaml}} (for example, enablement 
> and provider settings)
>  * Render corresponding {{impalad}} args only when OAuth is enabled
>  * Keep existing LDAP behavior unchanged and backward-compatible
>  * Document usage in chart examples and Kubernetes deployment docs
> *Testing*
>  * Run {{helm lint}} for the chart
>  * Run {{helm template}} and verify OAuth args are rendered only when enabled
>  * Deploy on a test Kubernetes cluster and validate {{impalad}} starts with 
> expected OAuth flags
>  * Verify no behavior change when OAuth config is omitted
> *Compatibility/Risk*
> Low risk. Defaults remain unchanged, and OAuth flags are opt-in.
