[jira] [Resolved] (YARN-7012) yarn refuses application if a user
has no groups associated
[ https://issues.apache.org/jira/browse/YARN-7012?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Wilfred Spiegelenburg resolved YARN-7012.
-----------------------------------------
Assignee: Wilfred Spiegelenburg
Resolution: Not A Bug
The group mapping you configure should handle the local and non local users. A user must have at least a primary group, it is needed for ownership of files etc.
The exception you see shows that the user is not considered valid and this is supposed to happen.

> Key: YARN-7012
> URL: https://issues.apache.org/jira/browse/YARN-7012
> Project: Hadoop YARN
> Issue Type: Bug
> Affects Versions: 2.7.3
> Environment: redhat 7.3
> Reporter: Michael Salmon
> Assignee: Wilfred Spiegelenburg
> Priority: Major
>
> When an application is submitted the list of queue mappings is searched for the default queue for the user submitting the application. If there is a queue mapping for a group and the user does not have any groups then an exception is thrown and the application is rejected:
> org.apache.hadoop.yarn.exceptions.YarnException: Failed to submit application application_1499325026025_0002 submitted by user hive reason: No groups found for user hive
> at UserGroupMappingPlacementRule.java:153 although the lookup is at line 122.
> This problem arises when using local users and AD groups.
> Users without groups should be treated as users with no matching groups
