CDP 7 placement rules dont work

Please share a screenshot of your placement rules

Hello @Scout 

First, we need to understand we tried to enable tag-based policy only for Hive jobs because those jobs submitted by proxy user hive. After we enable the tab-bases policy the job submitted with hive user instead of proxy user

Instructions

Step 1:

Enable application tag placement and whitelist hive

1. In Cloudera Manager, select the YARN service.
2. Click the Configuration tab.
3. Search for ResourceManager. In the Filters pane, under Scope, select ResourceManager.
4. In ResourceManager Advanced Configuration Snippet (Safety Valve) for yarn-site.xml add the following.
5. Set these two yarn configurations:

• yarn.resourcemanager.application-tag-based-placement.enable=true;
• yarn.resourcemanager.application-tag-based-placement.username.whitelist=hive;

Step 2:

You need to check, and if not found, add several configuration properties to allow placement of the Hive workload on the Yarn queue manager.

1. In Cloudera Manager, click Clusters > Hive on Tez> Configuration.
2. Search for the Hive Service Advanced Configuration Snippet (Safety Valve) for hive-site.xml setting.
3. In the Hive Service Advanced Configuration Snippet (Safety Valve) for hive-site.xml setting, click +.

• In Name enter the property hive.server2.tez.initialize.default.sessions and in value enter false.
• In Name enter the property hive.server2.tez.queue.access.check and in value enter true.
• In Name enter the property hive.server2.tez.sessions.custom.queue.allowed and in value enter true.

Next you need to add placement rules as below:

Add placement rules >> This rule matches = hive_user >> Custom policy = <yarn.queue.name> (where you want to submit the job.

Note: Order of policy also played vital role, please order properly to move the job in aligned queue.

Please share a specific use case, ie. Pick a sample user job that is expected to go to a specific queue and share its placement rules screenshot

Hi, I am not able to open a case but I work like a agent for cloudera , I was running the stock market and I am not able to withdraw my deposit since the system give me high package and I can’t manage to cover the overdraft again.. what can I do? 

  someone who can help me with this, I don’t want to lose my money? 

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?

Hi @Scout

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