Research direction

Review the linked PR (https://github.com/prestosql/presto/pull/1439) and StackOverflow question to understand the expected behavior of Hive's collection.delim property. Investigate how Trino's Hive connector currently handles collection delimiters and where the property needs to be parsed and applied. Examine the Hive connector code in the trino hive module to identify relevant files such as HiveTableProperties or similar classes. Note that this issue has been open since 2019 and may require re assessment of current codebase state.
