REST Example

The following output is an example of the service information returned when you issue the service list REST API call:

https://qa-node102.qa.lab:8443/rest/service/list?node=qa-node102.qa.lab

Note: When you configure high availability for the ResourceManager, the status of standby ResourceManager service differs based on the selected failover implementation. When the cluster uses manual or automatic failover for the ResourceManager, standby ResourceManagers have a state equal to 2 (running). When the cluster uses zero configuration failover for the ResourceManager, standby ResourceManagers have a state equal to 5 (stand by).
