Importing unix groups in to ranger groups/queue

[#1]

1) Can we import unix groups (group 1, group 2 etc) in to Ranger as groups direclty

2) Can we directly have yarn queues as per unix group ? Like group1 queue , group 2 queue

3) If user 1 is part of two yarn queues(queue1 and queue2) at the same time, which queue will user1 be allocated to?

[#2]

@Sushant

Ranger supports importing unix users and groups using /etc/passwd and /etc/groups files. And Ranger policies can be configured at the group level as well for all the services like hdfs, yarn, hive, etc...

For Question#3, it is up to yarn to allocate queue to the user. Ranger only authorizes the access for the user based on the configured policies.

Regarding yarn queues, how will yarn allocate resource to user , when it's part of multiple queues?
