Thejas M Nair commented on HIVE-5931:
-------------------------------------
The reason why 'describe function <funcname>' works is that for some historic
reason the keyword function was not marked as a non reserved keyword in
IdentifiersParser.g. This is not the case with ROLE keyword.
> SQL std auth - add metastore get_role_participants api - to support DESCRIBE
> ROLE
