thanks for finding this gap. this requires more visibility & tracking. We need to understand if it will fail any existing production views. can you please create a follow up ticket for identifying blast radius and mitigation strategy?

if you look at the git blame history for this unit test, you might be able to find out why this feature was needed at all

Good points — addressing both.

Origin (per git blame): testEnumUnionString was added in PR #282 (commit 6d6f10e, July 2022) alongside the SchemaUtilities.mergeUnionSchema enum∪string merge logic.

Root cause: The failure is in Hive 2.3.9's SemanticAnalyzer.UnparseTranslator.addTranslation during CREATE VIEW parsing — upstream of Coral. mergeUnionSchema itself is unchanged; queries against already-created views using this pattern still translate correctly.

Follow-up ticket: Filing one to track:

  • How many such views exist in prod today (enum∪string UNION pattern)
  • Mitigation options (e.g., explicit CAST(enum AS string) at view-author level, upstream Hive parser fix)
  • Re-enabling path for testEnumUnionString once a fix lands

Should this be a GitHub issue on this repo, or our internal tracker? Happy either way — let me know the preference.

public void testEnumUnionString() {
String viewSql = "CREATE VIEW v AS SELECT b1.Enum_Top_Col AS c1 FROM baseenum b1"
+ " UNION ALL SELECT b2.Struct_Col.String_Field AS c1 FROM basecomplex b2";

what is the new parameter in this API and what is the behavior?

Good question. The new second arg is boolean allowEmbedded.

Hive 2.3.9 removed the single-arg RetryingMetaStoreClient.getProxy(HiveConf). The closest replacement is getProxy(HiveConf, boolean allowEmbedded):

  • true → when hive.metastore.uris is unset (or points to localhost), the client brings up an in-process (embedded) HMS. This matches the Hive 1.2.2 behavior exactly — the old single-arg form always permitted the embedded path.
  • false → throws MetaException in that situation.

coral-service relies on the embedded path for local/test flows where no real metastore is configured, so true is the behavior-preserving 1:1 swap.

I've expanded the "Source fixes" section in the PR summary to include this semantic note, so future readers have the context inline.
