Cloudera Install default settings - adding increased host resources.

[#1]

When installing CM/CDH on a new cluster, is the configuration set according to available host resources?

Eg., if a cluster has 10 hosts. 3 hosts have 16 cores, 32G RAM and 3TB storage; 7 hosts have 8 cores, 16G RAM and 2TB storage

will CM (during install) create and adjusted config?  (EG., Java heap varied according to available resources, yarn localizer settings, etc)

Thus, if hosts are replaced/upgraded with increased available resources, the config settings will remain the same but it seems to me they should be manually adjusted to reflect new resources.  Can it be done via a script/Cmanager or is subsequent 'tuning' a manual task?

@TGH No, Cloudera manager will not adjust resources automatically whatever you will set per service base will be used by CM and services in the cluster.
