@Artem Ervits Yes thats what my understanding is. Thanks for confirming. By any chance is there a plan in future for cloudbreak to deploy cluster on already running VM's in cloud? ... View more

@Artem Ervits Is it possible to add nodes to cluster deployed using Ambari using cloudbreak? What i think is that cloudbreak can only add nodes to cluster spinned using cloudbreak UI. If yes, is there any reference links on adding/removing nodes using cloudbreak on cluster deployed using ambari? Thanks ... View more

@Artem Ervits I have already explored the cloudbreak option and got cluster up and running. It really fast. But the problem with cloudbreak is that it does not launch cluster on already running VM's in Azure and it launches new VM's for setting up cluster. We already have VM's running in Azure on which we want to setup cluster.That's why we are planning to go for Ambari installation. And for 2nd point, In dev environment since our data volume is less, we are keeping 3 data nodes and we would be keeping replication factor as 2. Will that work fine? Thanks ... View more

@Artem Ervits Ok. So once i copied the data from HDFS/OS mount points of old nodes to new nodes, then i can start decommissioning old nodes one by one. Please correct me if i am wrong? Thanks ... View more

@Artem Ervits Thanks for replying. After adding 2/3 new Slave Nodes to cluster using Ambari, Will the data be automatically copied into new Nodes? By Data I mean to say HDFS, and root/OS partition data. And will the nodes be rebalanced automatically by Ambari or is it to be done manually? ... View more

@apappu Thanks for the reply. If it is to be signed by self created CA or external CA then could you help in listing the steps for the same? Thanks ... View more

@apappu I followed the same link. I want to get my cert signed by own CA. so i was trying to follow the step 1. but i was not getting sure where should i run each each step(1-7) in case of 4 node cluster.(Edge, Namenode and 2 slave nodes)? ... View more
