Changing AWS Instance Type for HDP 2.5 Cluster

Changing AWS Instance Type for HDP 2.5 Cluster

Contributor

Hi, We are currently on HDP 2.5.3 running on AWS EC2 instance type m4.4xlarge with 16 CPUs and 64 GB memory. We need to change the Instance type from m4.4xlarge to m4.10xlarge (40 CPUs and 160 GB memory). Changing the Instance types does not harm any EBS volumes or data that is residing but are there any other issues post changing the instance type? If yes, what kind of issues we might face? If anyone has already succeeded, please brief me the steps prior to changing the instance type. Appreciate for response. Thank you.

Hi charan although you are making changes on Infra level which is on AWS so it will not effect on Any ambari service

You can follow following steps

1) Stop all the services from Ambari

2) Go to aws console stop instance

3) Change instance types which you want
