CDP 7 placement rules dont work

[#1]

Hi, trying to set placement rules as described in https://docs.cloudera.com/cdp-private-cloud-base/7.1.6/yarn-allocate-resources/topics/yarn-placement-rule-policies.html, but tasks still in default queue.

Also tried to enable tag-based authorization with the same result.

What could be wrong?

You do not have any value for the user name. "This rule mactches: users named <your_user>".
When you fill the rule you should set the name (or group, or application name) of the user that match your placement rule.

Username is set, but deteted due to security reasosns

[#4]

found in yarn logs records like 

failed to save service-tags to cache file '/var/lib/ranger/yarn/policy-cache/yarn_cm_yarn_tag.json'
java.io.FileNotFoundException: /var/lib/ranger/yarn/policy-cache/yarn_cm_yarn_tag.json (Permission denied)

Could it be the core reason? 

How can i fix it?

Hi @Scout 

Can you share acl for 

/var/lib/ranger/yarn/policy-cache/yarn_cm_yarn_tag.json
