             Summary: INFORMATION_SCHEMA.`FILES` table not show any files if storage contains "write only" folder
                 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


*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".

 

This bug can be reproduced on the "Amazon S3" and "File System"  Drill storage plugins.
