    Resolution: Not A Problem

> Spark shell fails if read permission is not granted to hive warehouse

>                 Key: SPARK-29078
>                 URL: https://issues.apache.org/jira/browse/SPARK-29078
>             Project: Spark
>          Issue Type: Bug
>          Components: SQL
>    Affects Versions: 3.0.0
>            Reporter: Mihaly Toth
>            Priority: Major
>
> Similarly to SPARK-20256, in {{SharedSessionState}} when 
> {{GlobalTempViewManager}} is created, it is checked that there is no database 
> exists that has the same name as of the global temp database (name is 
> configurable with {{spark.sql.globalTempDatabase}}) , because that is a 
> special database, which should not exist in the metastore. For this, a read 
> permission is required on the warehouse directory at the moment, which on the 
> other hand would allow listing all the databases of all users.
> When such a read access is not granted for security reasons, an access 
> violation exception should be ignored upon such initial validation.
