[jira] [Commented] (HIVE-19831) Hiveserver2 should skip doAuth checks for CREATE DATABASE/TABLE if database/table already exists

    [ https://issues.apache.org/jira/browse/HIVE-19831?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16876004#comment-16876004 ] 

Daniel Dai commented on HIVE-19831:
-----------------------------------

Can you add a comment saying when db exists, we would expect Hive throw an exception so there's no need to do the auth? Otherwise from the code, it seems we would skip the auth check when db exists.

> with sqlstdauth on, Create database if exists take TOO LONG if there are too many objects inside the database directory. Hive should not run the doAuth checks for all the objects within database if the database already exists.
