> h2. What
> Handle {{TimeType}} in Hive interop so Hive-serde tables and Hive UDFs do not
> fail on TIME,
> or, if full support is not feasible, produce a clear, documented error.
> h2. Why
> {{HiveInspectors}} has no {{TimeType}} case, so object-inspector creation and
> TypeInfo
> mapping fall through. Hive-serde tables and Hive ORC already reject TIME
> (SPARK-51590), but
> the behavior is implicit. Hive itself has no TIME type, so a faithful mapping
> is limited.
> h2. Scope
> Option A (preferred if viable): map {{TimeType}} through a Hive-representable
> carrier
> (e.g. string or {{TIMESTAMP}}) in {{HiveInspectors}} (toInspector / unwrap /
> wrap / TypeInfo
> paths) with documented semantics.
> Option B (fallback): detect {{TimeType}} early and raise
> {{UNSUPPORTED_DATA_TYPE_FOR_DATASOURCE}} (or a dedicated Hive error) with a
> clear message,
> and document the limitation on the TIME docs page.
> h2. Acceptance criteria
> * No {{MatchError}}/internal error when a TIME column reaches Hive serde
> paths.
> * Behavior (support or explicit error) is covered by tests in the hive module
> and documented.
