Walkthrough

HiveHelper methods now document table and partition operations and their expected failures. The Spark catalog and SQL implementations declare possible SQLException exceptions. Both implementations use partitionPath for the partition data path.

Changes

HiveHelper API updates

Layer / File(s)	Summary
Document the HiveHelper contract pramen/core/src/main/scala/za/co/absa/pramen/core/utils/hive/HiveHelper.scala	Documents table creation, schema replacement, partition management, table lookup, and table removal. Renames the partition schema method’s location parameter to partitionPath.
Align catalog and SQL implementations pramen/core/src/main/scala/za/co/absa/pramen/core/utils/hive/HiveHelperSparkCatalog.scala, pramen/core/src/main/scala/za/co/absa/pramen/core/utils/hive/HiveHelperSql.scala	Adds SQLException declarations to table and partition operations. Uses partitionPath when replacing a partition schema and when adding a missing partition.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Other

Merge Risk: 🔵 Low · up to 28653

The HiveHelper documentation can mislead callers about what happens when a partition is missing. Both implementations attempt recovery, though the retry may fail; this is a bounded issue with a straightforward documentation correction.

And hops through methods, line by line
A partition path gets a clearer name
SQLException joins the written signs
Then off I go, with docs in place!}

- Around line 128-129: Update the partition-replacement documentation in
HiveHelper to clarify that the table must exist, while a missing partition
triggers an attempt to add it and retry replacement; note that the call can
still fail if the retry fails, typically with SQLException.
