------------------------------------
Summary: FileUtils. isActionPermittedForFileHierarchy,
isOwnerOfFileHierarchy file system operations should be impersonated
Key: HIVE-16497
URL: https://issues.apache.org/jira/browse/HIVE-16497
Project: Hive
Issue Type: Bug
Components: Authorization
Reporter: Thejas M Nair
Assignee: Thejas M Nair
Fix For: 3.0.0
FileUtils.isActionPermittedForFileHierarchy checks if user has permissions for
given action. The checks are made by impersonating the user.
However, the listing of child dirs are done as the hiveserver2 user. If the
hive user doesn't have permissions on the filesystem, it gives incorrect error
that the user doesn't have permissions to perform the action.
Impersonating the end user for all file operations in that function is also
logically correct thing to do.
