> - {{'yarn.timeline-service.entity-group-fs-store.app-cache-size'}} on cluster initialization/creation
based on host memory.
> - {{'apptimelineserver_heapsize'}} on : (1). cluster initialization/creation and/or (2).
when a change is detected in value for {{'yarn.timeline-service.entity-group-fs-store.app-cache-size'}},
using formula:
