Subject tablet server not using all resources availables
Date Fri, 19 Apr 2019 11:37:34 GMT
Dear Kudu community,

We have a test kudu cluster with 3 vms and each one of them has a master and a tablet server.

Each vm has:
x50 vcpus
500 MB RAM
4TB virtual disks with xfs on local hypervisor nvme drives

We started an ETL process using apache spark and realised that the vms are not fully utilised
(~15 vcpus are used and the iowait time is 0). That tell us that kudu is not using all the
resources available on the machine and the system is not fully optimised.


How could we configure the tablet server to fully utilize the resources available?
Is it a good practice to run multiple tablet server on the same vm?

thank you very much
