Hi Deborah Littlefield Community Manager


I have uninstalled the mapr from the Cluster B nodes. I am just a newbie with mapr Admin. Where do i have to run the mapr installer? on the existing cluster node or on the new node for adding the new nodes to the Cluster A.


and my existing cluster is running with

3 zookeeper,

1 cldb,

1 nfs instances and am gonna add each 1 more instances for cldb and nfs. 

what else i have to keep in my mind with the service layout for adding new nodes to the cluster!??


Really appreciate your insight and guidance in this.
