---------------------------------------
Summary: Add OAuth authentication options to Impala Helm chart
Key: IMPALA-15016
URL: https://issues.apache.org/jira/browse/IMPALA-15016
Project: IMPALA
Issue Type: Task
Reporter: Anubhav Jindal
Assignee: Anubhav Jindal
*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.
