[jira] [Updated] (HIVE-8424) Support fair scheduler user queue
mapping in non-impersonation mode
[ https://issues.apache.org/jira/browse/HIVE-8424?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Mohit Sabharwal updated HIVE-8424:
----------------------------------
Description:
Under non-impersonation mode, all MR jobs run as the hive system user. The 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.
was:
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.
