> Key: DRILL-6858
> URL: https://issues.apache.org/jira/browse/DRILL-6858
> Project: Apache Drill
> Issue Type: Bug
> Affects Versions: 1.15.0
> Reporter: Denys Ordynskiy
> Assignee: Arina Ielchiieva
> Priority: Major
> Fix For: 1.15.0
>
>
> *Steps to reproduce bug:*
> * storage contains folder with "write only" permission;
> * Drill option "storage.list_files_recursively" is false;
> * query result for "SELECT * FROM INFORMATION_SCHEMA.`FILES`;" shows the
> list of the files and folders for every workspace for each storage plugin;
> * set Drill option "storage.list_files_recursively" to true;
> * run query "SELECT * FROM INFORMATION_SCHEMA.`FILES`;"
> *Actual result:*
> Drill returns empty results table if workspace has a folder with "write only"
> permission. Even if this workspace contains files and folders, that have
> "read" access right.
> *Expected result:*
> Drill returns list of files for each folder with "read" permission and hide
> files list for "write only" folders. Showing only folders name when
> permission is "write only".
>
