The HBase Service
Cloudera Manager requires certain additional steps to set up and configure the HBase service.
Creating the HBase Root Directory
When adding the HBase service, the Add Service wizard automatically creates a root directory for HBase. If you quit the Add Service wizard or it does not finish, you can create the root directory outside the wizard by doing these steps:
- Choose Create Root Directory from the Actions menu in the HBase > Status tab.
- Click Create Root Directory again to confirm.
Graceful Shutdown
Cloudera Manager provides the following configuration options to perform a graceful shutdown of either an HBase RegionServer or the entire service:
To gracefully shut down an HBase RegionServer:
- Navigate to the HBase Service > Instances tab.
- From the list of Role Instances, select the RegionServer you want to shut down gracefully.
- From the Actions for Selected drop-down menu, select Decommission (Graceful Stop).

To gracefully shut down the entire service:
- Navigate to the HBase service and from the Actions menu, select Stop... This tries to perform an HBase Master-driven graceful shutdown for three minutes (by default), after which it abruptly shuts down the whole service.
To configure the Graceful Shutdown Timeout:
- Navigate to the HBase Service > Configuration tab and select View and Edit.
- Under the Service-Wide category, scroll down to the Graceful Shutdown Timeout property and click on the current Value to change it.
- Click Save Changes to save this setting.
- Restart the HBase service (Actions > Restart...) for this change to take effect.
