I set only my IP, Doubled RAM    I know that enabling the Kerberos resolve that issue but in previous versions 5.12 (May-June) everything was working by default without  problem on smaler configuration.     huh     Thanks   ... View more

Thanks for response, don`t know what to do. 1. Completely new cluster setup 4 nodes on Amazon WS (idle) Cloudera 5.15.1 RedHat 7.5 Cloudera SCM with all main roles on t2.x2large  -- 16 GB RAM Data nodes t2.medium  4 GB RAM Cluster new, without load 2. Cluster exposed to internet on ports (22,50070,19888,8042,7180,8020,7432,7182-7183,8088, ICMP) I use inbound/outbound rules for  security group on AWS (not enough) 3.  [ec2-user@ip-172-31-35-169 ~]$ sudo -u yarn crontab -l no crontab for yarn   Thanks       ...
