The rra directory is (usually) created as a subfolder of the cacti directory. In this case, this resolves to /var/www/html/cacti.
The error printed for your examples is mostly a cause of negative results for downed host detection.
Cacti checks each host prio to retrieve data. This is done to avoid a timeout for each and every data source in case there are lots per host. For a downed host, this would spend a huge amount of the polling time.
For a SNMP aware host, I recommend using downed host detection method "SNMP", not ping.
