Kyuubi service management via ADCM

Sergei Tikhomirov

The ADCM UI provides actions to manage the Kyuubi service and its components. For information on how to run service actions, refer to ADH service actions.

The actions available for the Kyuubi service are listed in the table below.

Action Description

Check

Runs service-specific tests to check the health of the service and its components

Start

Starts the service. When you run this action, the option Apply configs from ADCM is available. If it is set to true, all service configurations defined in ADCM settings will be applied on the service startup. Otherwise, the service starts without applying configurations from ADCM

Stop

Stops the service

Restart

Restarts the service. When you run this action, the option Apply configs from ADCM is available. If it is set to true, all service configurations defined in ADCM settings will be applied during the service restart. Otherwise, the service restarts without applying configurations from ADCM

Remove

Removes the service from the cluster. This action should be used to remove already installed services. Whereas the delete control can be used to remove a non-mapped service (a service which components have not been distributed among cluster hosts)

IMPORTANT

In order to use a query engine (e.g. Flink SQL/Hive/Spark SQL), it’s required to map a corresponding service’s client onto the Kyuubi’s host. For common configurations, just HDFS and YARN clients are required.

Kyuubi has just one component — Kyuubi Server, which has actions of its own.
