cloudera - how to allocate resources for different users

Question

I am using cloudera 6.3 and trying to achieve following things.

1. all the users who are running interactive queries should not get more than 20% of resources
2. Functional id which is used for getting data through Imapala should not get 30% of resources
3. functional is's which are being used for ETL should get minimum 70% of resources, however if required should take resources from above two.

What should I need to do ?

1. do I need to configure dynamic resource pool for 1 and 2 ? or do I need yarn queue
2. for points 3 do I need to configure resouce pool from imapala admission control ?

What does this means ? what does root.default and root.users represents ?

Answer 1

root is the root queue, as the name suggests. root.default and root.users are its sub-queues (you can tell by the fact there is the prefix root.).

Honestly I'm not sure that Impala uses YARN to manage its resources though
