Looking at the docs for installing CDAP for mapr hadoop systems by the MapR partner Cask, it hints at the possibility of 'installing on and edge-node' (https://docs.cask.co/cdap/current/en/admin-manual/installation/mapr.html#create-the-cdap-user). My question (for any other MapR users that have used CDAP) is: by 'edge-node', does this refer to a node that is neither a data-node or control-node on the cluster but rather any machine running the mapr-client software (enabling it to submit mapred. and yarn jobs, as well as run hadoop fs commands) (https://maprdocs.mapr.com/home/AdvancedInstallation/SettingUptheClient-mapr-client.html) able to interact with the cluster? So does this mean that CDAP could be, for example, installed on a dedicated server that uses the mapr-client software (rather than on the cluster itself)? Thanks.
