[jira] [Commented] (IMPALA-11245) Inaccurate tips with 'select' on not exist table

["Quanlong Huang (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IMPALA-11245?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17712145#comment-17712145 ] 

Quanlong Huang commented on IMPALA-11245:
-----------------------------------------

Sorry to miss this..

I think the current behavior makes sense. As the comment pointed out, we prefer reporting an authorization error over an analysis error, since we should not accidentally reveal the non-existence of a table/database if the user is not authorized.

>    Affects Versions: Impala 4.0.0, Impala 3.4.0

> {code:java}
> select count(1) from db.test;{code}
> Both database 'db' and table 'test' are not exist. This will get error "{_}AnalysisException: Could not resolve table reference: 'db.test'{_}".
> If enabled Ranger then get error "{_}AuthorizationException: User 'xx' does not have privileges to execute 'SELECT' on default.db{_}".
> Actually maybe "{_}Table does not exist: db.test{_}" is more friendly tip :) .   Just like 'insert into db.test' gives error "{_}AnalysisException: Database does not exist: db{_}".
