[jira] [Commented] (HIVE-9350) Add ability for HiveAuthorizer implementations to filter out results of 'show tables', 'show databases'

["Alexander Kolbasov (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-9350?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16195480#comment-16195480 ] 

Alexander Kolbasov commented on HIVE-9350:
------------------------------------------

[~thejas] What was the reason for adding {{MetaException}} and {{NoSuchObjectException}} to {{MetaStoreFilterHook}} interfaces? Looks like the only implementation isn't throwing any exceptions.

The problem is that the change requires clients to recompile against the new interface.

> It should be possible for HiveAuthorizer implementations to control if a user is able to see a table or database in results of 'show tables' and 'show databases' respectively.
