Hi We currently have a cluster of 3 nodes, all of same configuration[4cpu, 8GB RAM, 2TB]. Namenode website shows that DFS used % is 30%[Nearly 700GB used per node]. The CPU utilization is continuously remaining high for all the nodes in cluster. So to fit to the needs of growing number of jobs that we are submitting to hadoop cluster, planning to add more boxes [of smaller capacity, 2cpu, 8GB RAM, 150GB]. So in long term, we want to grow the cluster with many smaller capacity boxes and replace the larger capacity boxes. To start off we may be having a some of large boxes and some of smaller ones in the cluster. Will this setup work fine.
Thanks & Regards Sandhya
