--------------------------------
Summary: Use FileSystem.access() if available to check file access
for user
Key: HIVE-7583
URL: https://issues.apache.org/jira/browse/HIVE-7583
Project: Hive
Issue Type: Bug
Reporter: Jason Dere
Assignee: Jason Dere
Hive currently implements its own file access checks to determine if a user is
allowed to perform an specified action on a file path (in
StorageBasedAuthorizationProvider, also FileUtils). This can be prone to errors
or inconsistencies with how file access is actually checked in Hadoop.
HDFS-6570 adds a new FileSystem.access() API, so that we can perform the check
using the actual HDFS logic rather than having to imitate that behavior in
Hive. For versions of Hadoop that have this API available, we should use this
API.
