Hyungro's comment

  • can we minimize/change the size of the base system? Let's say, no zk, 1 master and 1 data and no monitor. It seems we can change values in .cluster.py but I am not sure the default values are minimal e.g. 3 zk, 3 master.

Setup the default deployment to be non-HA. Flip to HA by setting a hadoop_ha_mode=true either in --extra-vars or in host_vars/all.
