The Authorization mechanisms in hive are not as solid as other RDBMS. A user can grant himself rights and can then drop a table or do whatever operations he likes to do. There is no super user(admin) and sub user concept in hive yet, but the community is having plans to implement that in future with strong Authorization mechanisms.
Saying this if the business users are guaranteed not to play with GRANT statements or rather not change permissions themselves, (But it is hard to guarantee this when the no of users are large :) ) hive can satisfy your requirement.

Take a look at this, https://cwiki.apache.org/Hive/languagemanual-auth.html. This may be what you are looking for .

My use case requires individual accounts for business users groups. Is there a way to mimic MySQL (or other database) to create users with read-only permissions? This avoid business user accidental table drop. Metastore has table ROLES but don’t see documentation on that. Much appreciated if anyone can point to the documentation or share your thoughts on this?
