Description

Contributor guide

Research direction

Examine the referenced PRs (https://github.com/prestosql/presto/pull/1439) and the StackOverflow question to understand how Hive collection.delim property is expected to work. Then review the Trino Hive connector code where table properties are parsed and applied, particularly in the HiveMetadata and related classes. Trace the property through the CREATE TABLE and INSERT OVERWRITE DIRECTORY paths to identify where support needs to be added.
