Thanks Darren. We got decommission RegionServer service to work, but recommission command does not work - we get a 404 error when we attempt to run command below. http://d2phantd05:7180/api/v1/clusters/Cluster%201%20-%20CDH4/services/hbase1/commands/recommission Note we are not running decommission host, as it would force hfds data to get re-distributed, which is not required. Any insights you can share on recommission RegionServer CM API will be greatly appreciated.

Hi, We are trying without much success to figure out how to use CM API library to gracefully shutdown and then startup services running on specific nodes in the CDH cluster. We need to take down nodes for maintenance for few hours and need to keep the overall cluster up and running. For example if the node is a data node and is running Hbase region server, then the script for that node should stop region server gracefully, and then stop task tracker and data node daemon running on that node. Browsing through the CM API library, I dont see APIs for us to do this. I do see some stop and start APIs but cannot figure out how to call them. We are using Python. Any insights would be appreciated.
