Related work and retirement guidance

Recreates the current-master intent of chore: remove all refs to azure CDN #2326 without closing or modifying that PR.
Azure CDN Standard from Microsoft (classic) retirement FAQ
Migration guidance to Azure Front Door Standard/Premium
Azure Front Door and Azure CDN comparison

What changed

Replaced all 400 audited current-master references to mmlspark.azureedge.net in 139 files with the repository-owned mmlspark.blob.core.windows.net origin.
Covered runtime Scala/Python configuration, generated Maven/R resolver metadata, docs, notebooks, build/release examples, website generation/UI, and all 21 versioned-doc sets.
Repaired current and versioned R setup guidance after review found that published wrapper archives still embed the retired resolver:
- use all six version-matched component archives (the documented combined archives do not exist);
- configure the Blob Maven resolver explicitly and suppress embedded sparklyr registrations with extensions = character();
- configure the JVM package before a Databricks cluster starts;
- correct the LightGBM R API example.
Removed two mvnrepository.com/artifact/... HTML pages from the Docker demo's Maven repository list; Maven Central remains Spark/Ivy's default for those dependencies.
Added regressions for generated R resolver metadata and R-guide version/archive consistency.

Why direct Blob Storage

SynapseML's release tasks publish Maven, docs, notebooks, badges, and R artifacts directly to the mmlspark storage account.
Current master already contains more than 6,000 direct references to this Blob Storage origin.
DNS and response comparisons show the legacy hostname fronts the same Blob origin; every successful audited old/new path was byte-identical.
The Blob origin is verifiable and repository-owned. This PR does not invent an unverified Front Door hostname.

Published R archive limitation (scope clarification)

This is a source-and-documentation migration; it does not claim that already-published R ZIP contents were rewritten. The component archives for the documented releases still contain generated sparklyr metadata naming the retired resolver. Current source generation now emits the Blob resolver, but repairing historical artifact metadata requires an external publishing action.

The repository-controlled installation path in this PR was tested with the legacy hostname made unresolvable: install the Blob-hosted, version-matched component archives; pass the aggregate Maven coordinate and Blob repository explicitly; and use extensions = character() so sparklyr ignores the embedded registration.

Exact prerequisite for full artifact migration: a maintainer with authorized write access to the mmlspark/rrr Blob container must regenerate and publish the six supported component archives with the updated RCodegen/PackageUtils output (or publish replacement release versions), then verify the published package_register.R metadata. This PR intentionally does not overwrite release artifacts.

Validation

Audited/classified all 400 original references: Maven (218), R archives (154), PySpark API docs (23), datasets/models (4), icon (1).
Compared all 32 unique old/new URLs: matching status and byte-identical bodies for every successful response.
Confirmed all 126 unique version-matched R component archive URLs (21 releases × 6 modules) return HTTP 200 with non-empty bodies.
Installed all six 1.1.3 R wrappers from Blob and confirmed their embedded legacy registration.
Under a process-local DNS blocker for the retired hostname and a fresh Ivy cache:
- the archive's default extension registration failed as expected;
- the documented explicit Blob configuration connected successfully;
- ml_clean_missing_data transformed all 272 rows;
- the corrected LightGBM example trained/transformed all 272 rows;
- Spark logs contained no legacy-host access.
Resolved com.microsoft.azure:synapseml_2.12:1.1.3 and all module dependencies through the Blob resolver.
sbt -batch "core/Test/testOnly com.microsoft.azure.synapse.ml.codegen.VerifyRCodegen" — 1 passed.
sbt -batch scalastyle test:scalastyle core/Test/compile — passed.
black==22.3.0 --check --extend-exclude 'docs/' . — 179 files unchanged.
npm test — 24 passed; npm run build — production build succeeded.
git diff --check; zero tracked legacy-host references; zero mvnrepository.com/artifact repository entries.
Independent code review found no significant issues.

Pre-existing dead paths

The former combined R archive URLs and two directory-style dataset/model URLs were already 404 through both the CDN and Blob origin. The combined R links are now removed from the setup guides in favor of the published component archives. No dead artifact is presented as newly repaired by a hostname substitution.

## Summary Replace all 400 current-master references to mmlspark.azureedge.net with the repository-owned mmlspark Blob Storage origin across runtime package configuration, release output, examples, documentation, notebooks, and every published documentation version. ## Prompting Intent Recreate the intent of the stale CDN-removal PR on current master only after verifying the supported artifact destination and Azure CDN retirement path. Audit each endpoint use by semantics, preserve package and content paths, validate live artifacts and package resolution, and avoid changing or closing the original PR. ## Linked Sources - Original proposal: microsoft#2326 - Azure CDN retirement FAQ: https://learn.microsoft.com/en-us/azure/cdn/classic-cdn-retirement-faq - Azure CDN migration guidance: https://learn.microsoft.com/en-us/azure/cdn/migrate-tier - Azure Front Door/CDN comparison: https://learn.microsoft.com/en-us/azure/frontdoor/front-door-cdn-comparison ## Rationale SynapseML's release pipeline publishes artifacts directly to the mmlspark storage account, the repository already uses that public Blob Storage origin extensively, and byte-for-byte URL checks confirmed the CDN currently proxies the same content. Using the verified origin removes the retiring CDN hostname without inventing an unverified Front Door name, while preserving Maven, documentation, R-package, model, dataset, and icon path semantics. Historical links that already return 404 retain the same status and are not broadened into unrelated artifact-repair work. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

## Summary Repair current and versioned R setup guidance so each release installs its six published, version-matched component archives and resolves SynapseML JVM artifacts through Blob Storage. Document the compatibility bypass required by already-published wrappers, correct the Databricks setup and LightGBM example, remove invalid HTML-page Maven repositories from the Docker demo, and add generator/docs regressions. ## Prompting Intent Investigate the review finding that published R archives still register the retired Azure CDN resolver. Make repository-controlled R installation work with that hostname unavailable, avoid claiming that externally published archives were rewritten, validate local and Databricks-oriented resolution paths, and state the exact external publishing prerequisite for a full artifact migration. ## Linked Sources - Original migration PR: microsoft#2326 - Current migration PR: microsoft#2589 - Maven repository review: microsoft#2589 (comment) - Azure CDN retirement FAQ: https://learn.microsoft.com/en-us/azure/cdn/classic-cdn-retirement-faq - Azure Front Door migration guidance: https://learn.microsoft.com/en-us/azure/cdn/migrate-tier - Apache Spark package repository configuration: https://spark.apache.org/docs/3.5.0/configuration.html#runtime-environment ## Rationale Existing release archives cannot be repaired by a source-only change because their generated sparklyr metadata is already published. Version-matched component downloads plus an explicit Blob resolver and `extensions = character()` provide a tested repository-controlled path without racing or misrepresenting external publication. Future generated archives inherit the corrected resolver from PackageUtils; fully repairing historical metadata still requires an authorized regeneration and publish to the `mmlspark/rrr` container (or a replacement release).

R completeness follow-up is ready for re-review in 9f1ddcf. The guides now use version-matched component archives, explicitly route Maven resolution to Blob, suppress the published wrappers' embedded retired-resolver registration, and configure Databricks before cluster start. I validated all 126 archive URLs and ran real R/Spark core + LightGBM examples with the legacy hostname made unresolvable. The PR description now explicitly scopes the remaining external prerequisite: authorized regeneration/republication of historical wrapper archives. The prior Maven HTML-page review is fixed and resolved. Please re-review the updated diff.

The inline comment in the Python install snippet says to use SynapseML 1.1.3 for both Spark 3.5 and Spark 3.4, but elsewhere (including the SBT snippet just below) the Spark 3.4 guidance is 1.0.15. This is misleading for users copying the snippet.

                    snippet={`import pyspark
spark = (pyspark.sql.SparkSession.builder.appName("MyApp")
        .config("spark.jars.packages", "com.microsoft.azure:synapseml_2.12:1.1.3") # Please use 1.1.3 version for Spark3.5 and 1.1.3 version for Spark3.4

## Summary Correct the Spark Packages and Python installation snippets so both identify SynapseML 1.0.15 as the compatible release for Spark 3.4 while retaining SynapseML 1.1.3 for Spark 3.5. ## Prompting Intent Address the remaining actionable review feedback on PR microsoft#2589 in the existing branch, verify the surrounding compatibility guidance stays consistent, run targeted website validation and code review, and rerun the full PR checks. ## Linked Sources - Pull request and review feedback: microsoft#2589 - Original migration context: microsoft#2326 ## Rationale The Databricks, Fabric, and SBT guidance already distinguishes SynapseML 1.1.3 for Spark 3.5 from 1.0.15 for Spark 3.4. Updating only the two stale explanatory references restores consistency without changing the Spark 3.5 commands that the snippets demonstrate.

Azure Pipelines: Successfully started running 1 pipeline(s).

## Summary Merge the latest master commits into microsoft#2581 after restoring the stacked CI changes and extending the Docker validation budget. ## Prompting Intent The engineer asked to refresh the parent PR against master, preserve all merged stack changes, and continue full validation until the current merge candidate is ready. ## Linked Sources - Parent PR: microsoft#2581 - CDN migration merged to master: microsoft#2589 - Azure Search AAD authentication merged to master: microsoft#2591 ## Rationale Merging master preserves the existing reviewed branch history and the official stack recovery commit without rewriting the fork. The merge is conflict-free, keeps the Docker timeout regression fix intact, and ensures the next Azure run tests the actual current integration candidate rather than a stale base.
