> YARN queue mapping fails for users with no group
> ------------------------------------------------
>
> Key: YARN-6261
> URL: https://issues.apache.org/jira/browse/YARN-6261
> Project: Hadoop YARN
> Issue Type: Bug
> Reporter: Pierre Villard
> Assignee: Daniel Templeton
>
> *Issue:*
> Since Hadoop group mapping can be overridden (to get groups from an AD for
> example), it is possible to be in a situation where a user does not have any
> group (because the user is not in the AD but only defined locally):
> {noformat}
> $ hdfs groups zeppelin
> zeppelin:
> {noformat}
> In this case, if the YARN Queue Mapping is configured and contains at least
> one mapping of {{MappingType.GROUP}}, it won't be possible to get a queue for
> the job submitted by such a user and the job won't be submitted at all.
> *Expected result:*
> In case a user does not have any group and no mapping is defined for this
> user, the default queue should be assigned whatever the queue mapping
> definition is.
> *Workaround:*
> A workaround is to define a group mapping of {{MappingType.USER}} for the
> given user before defining any mapping of {{MappingType.GROUP}}.
