> Project: Hive
> Issue Type: Bug
> Reporter: Raghav Aggarwal
> Assignee: Raghav Aggarwal
> Priority: Major
>
> Currently, _SHOW COLUMNS_ uses a manual string replacement for the _*_
> wildcard and fails to support standard SQL wildcards ({_}%{_} and _). This
> creates an inconsistent experience compared to _SHOW TABLES_ or {_}SHOW
> DATABASES{_}. This change refactors _ShowColumnsOperation.java_ to use the
> centralized _UDFLike_ translation engine, enabling modern SQL wildcards while
> preserving legacy glob support
