Hi,   I face the following problem. I have a service user say "service_dwh" used for our datawarehouse that queries heavily our data reservoir using hive queries. I have had some cases where due to the query and/or to missing statistics a single hive query could take 100% of the resources available for the "service_dwh" user. I couldn't find a way using capacity scheduler, queues and user limit factor to prevent a single application from taking all the resources for a very long time. Traditional DBMS have mechanism that throttle job resources based of the job duration. That way a long (big) job can't monopolyze ressources for new and potentially shorter jobs for too long. ...

Hi, I am provisionning a CDP 7.1.5 cluster with CM 7.2.4  and encountered a connexion problem between the agents and cloudera manager server after tls setup through API. There is nothing in the server log and there is the following error in the agent log. Could you help me understand where the problem stands ? Activating further logging or doing some tests upon the provided certificates ?
