> Enable end-to-end test execution against Kubernetes deployments

> Key: IMPALA-15043
> URL: https://issues.apache.org/jira/browse/IMPALA-15043
> Project: IMPALA
> Issue Type: Task
> Reporter: Anubhav Jindal
> Assignee: Anubhav Jindal
> Priority: Major
>
> h3. Background
> Impala now has upstream Kubernetes deployment support (Helm/operator), but
> upstream automated runtime validation is still centered on the local
> minicluster model.
> h3. Problem
> Current {{custom_cluster}} tests are not a good fit for Kubernetes validation
> because they restart local daemons between tests via minicluster tooling.
> This creates a gap: we lack an upstream-supported way to run meaningful E2E
> coverage against a real, externally deployed K8s Impala cluster.
> h3. Proposal
> Add an external-cluster/Kubernetes test mode that can run existing end-to-end
> style tests against a pre-provisioned K8s cluster without invoking
> minicluster start/stop flows. Reuse existing test harness pieces where
> possible, while clearly separating this mode from restart-dependent
> {{custom_cluster}} behavior.
> h3. Initial Scope
> * Add configuration/entrypoint support for connecting test clients to
> external Impala/Kudu/HMS endpoints.
> * Define and enable a stable initial E2E subset compatible with persistent
> external clusters.
> * Document setup, required inputs, and execution steps for manual and CI
> runs.
> h3. Out of Scope (Initial)
> * Full migration of restart-dependent {{custom_cluster}} coverage.
> * Replacing existing minicluster-based CI jobs.
> * Covering all optional auth/security permutations in the first iteration.
> h3. Success Criteria
> * Reproducible command path for running E2E tests against Kubernetes.
> * At least one stable upstream test suite running in this mode.
> * Existing minicluster workflows remain unchanged.
> h3. Testing
> * Manual validation against a Kubernetes test cluster.
> * CI validation for the new external-cluster mode.
> * Regression checks confirming no breakage to current minicluster test
> execution.
