> Some error messages in PrivilegeSpec are confusing. For example:
> https://github.com/apache/impala/blob/d753600f9cf4bda0c955f0f5eecc6fb41b0c365e/fe/src/main/java/org/apache/impala/analysis/PrivilegeSpec.java#L204-L206
> https://github.com/apache/impala/blob/d753600f9cf4bda0c955f0f5eecc6fb41b0c365e/fe/src/main/java/org/apache/impala/analysis/PrivilegeSpec.java#L254-L258
> https://github.com/apache/impala/blob/d753600f9cf4bda0c955f0f5eecc6fb41b0c365e/fe/src/main/java/org/apache/impala/analysis/PrivilegeSpec.java#L287-L289
> We should still aim to not reveal the existence of an object, however the message "Error setting privileges" and "Verify that you have permissions to issue GRANT/REVOKE statement" can be misleading since PrivilegeSpec is also used for "SHOW GRANT", which doesn't set any privileges.
