Hi, We are currently on HDP 2.5.3 running on AWS EC2 instance type for all the 17 datanodes m4.4xlarge with 16 CPUs and 64 GB memory. We need to change the Instance type from m4.4xlarge to r5.4xlarge (16 CPUs and 128 GB memory). Does Changing the Instance types with increased memory requires any data node hadoop configuration changes ? Do we need to modify any particular Master /data node hadoop configs to utilizes the additional memory ? please brief me the steps prior to changing the instance type. Appreciate for response. Thank you.
