-------------------------------

             Summary: hive.security.command.whitelist doesn't work for 'reload 
function'
                 Key: HIVE-15252
                 URL: https://issues.apache.org/jira/browse/HIVE-15252
             Project: Hive
          Issue Type: Bug
          Components: Authorization
            Reporter: Chao Sun
            Assignee: Chao Sun
            Priority: Minor


Right now the 'reload function' is handled specially in {{HiveCommand#find}}:
{code}
        return null;
      } else if(command.length > 1 && "reload".equalsIgnoreCase(command[0])
          && "function".equalsIgnoreCase(command[1])) {
        //special handling for SQL "reload function"
        return null;
      }
{code}

However, this means the {{hive.security.command.whitelist}} doesn't work for 
the command. It's better to first do the privilege check and then the rest.
