Can you enable NiFi on Oracle virtualbox - Hortonworks Sandbox HDP 2.6.5 with only 10 GB of RAM? If that's possible can you advise how? Please note I am using the OVA downloaded from Cloudera directly.
According to the tutorial section Enable Connected Data Architecture (CDA) you would need a minimum 22 GB of RAM. I am assuming that figure is over and above the minimum 10 GB RAM dedicated to the virtual machine for the HDP Sandbox. So while it might be possible to get it all to work together with only 10 GB of RAM, it will probably be unusable for most practical purposes.
