CDP 7 placement rules dont work

avatar
Contributor

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.

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?
