-------------------------------------
Summary: Support fair scheduler user queue mapping in
non-impersonation mode
Key: HIVE-8424
URL: https://issues.apache.org/jira/browse/HIVE-8424
Project: Hive
Issue Type: Improvement
Components: Shims
Reporter: Mohit Sabharwal
Assignee: Mohit Sabharwal
Under non-impersonation mode, all MR jobs will run with identity of hive system
user. This is because default scheduler queue mapping is one queue per user.
This is problematic for users who use the queues to regulate and track their MR
resource usage.
Yarn exposes an API to retrieve the fair scheduler queue mapping, which we can
use to set the appropriate MR queue for the current user.
