Is there a way to create user account and grant read only permissions?

[Patrick Luo]

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?
