Restart multiple components
Use a rolling restart to restart multiple components.
Rolling restarts of DataNodes should be performed only during cluster maintenance.
- In Services, click a service name.
In Summary, click a link, such as DataNodes or
RegionServers, of any components that you want to restart.
The Hosts page lists any host names in your cluster on which that component resides.
- Using the host-level Actions menu, click the name of a slave component option. Then, click Restart.
- Review and set values for Rolling Restart Parameters.
- Optionally, reset the flag to restart only components with changed configurations.
Click Trigger Rolling Restart.
