Hello, While configuring the yarn reports on CM, I am getting the error when the job CMYarnUsageAggregation job runs. Now user 'abc' is what is configured to run the mapreduce job. The resource pool is created under root-users-abc. However I am still getting the error. Any idea why?

Hello, After running few sqoop jobs (medium sized jobs) , I tried to check the CPU usage using the charts-chart builder with the following SQL. SELECT yarn_reports_containers_used_cpu FROM REPORTS WHERE category=SERVICE AND clusterName=ETL_DEV; I get the error that No entities found matching filter 'clusterName = "ETL_DEV"' in 'SELECT yarn_reports_containers_used_cpu FROM REPORTS WHERE category=SERVICE AND clusterName=ETL_DEV'. I also don't see anything under clusters-utilization report- YARN. I did enable the yarn metrics collection with "Enable Container Usage Metrics Collection". Could you let me know if I am missing anything? Thanks

Hello Consult, I get no output with 7180 as well. Actually we use port 7183. I actually found the issue however still have not been able to fix it though. The MySQL database service was not running. I tried restarting the service however got the belwo issue. ./mysql restart MySQL server PID file could not be found! [FAILED] Starting MySQL.180111 08:22:38 mysqld_safe Logging to '/var/lib/mysql/xx.xxx.xxxx.local.err'. 180111 08:22:38 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql ..... [FAILED] Failed to restart server. So I tried creating the PID file “mysqld.pid” in /var/run folder and tried starting the service again , did not work. Got the same error. I checked the /var/lib/mysql/xx.xx.xxx.local.err' and here is what I see. 2018-01-11 8:22:38 140075450689504 [ERROR] InnoDB: Operating system error number 13 in a file operation. 2018-01-11 8:22:38 140075450689504 [ERROR] InnoDB: The error means mysqld does not have the access rights to the directory. 2018-01-11 8:22:38 140075450689504 [ERROR] InnoDB: Operating system error number 13 in a file operation. 2018-01-11 8:22:38 140075450689504 [ERROR] InnoDB: The error means mysqld does not have the access rights to the directory. 2018-01-11 8:22:38 140075450689504 [ERROR] InnoDB: Cannot open datafile './ibtmp1' 2018-01-11 8:22:38 140075450689504 [ERROR] InnoDB: Unable to create the shared innodb_temporary 2018-01-11 8:22:38 140075450689504 [ERROR] InnoDB: Plugin initialization aborted with error Cannot open a file 2018-01-11 8:22:43 140075450689504 [Note] InnoDB: Starting shutdown... 2018-01-11 8:22:43 140075450689504 [ERROR] Plugin 'InnoDB' init function returned error. 2018-01-11 8:22:43 140075450689504 [ERROR] Plugin 'InnoDB' registration as a STORAGE ENGINE failed. 2018-01-11 8:22:43 140075450689504 [Note] Plugin 'FEEDBACK' is disabled. 2018-01-11 8:22:43 140075450689504 [ERROR] Could not open mysql.plugin table.
