Move Spark History Server |
Moves the Spark History Server component to a different host. Use the force option if the source host (where the service is currently installed) is offline |
Remove Spark History Server |
Removes the Spark History Server component. Running this action opens the component-host mapping interface where you can remove History Server components |
Move Spark Livy |
Moves the Spark Livy Server component to a different host. Use the force option if the source host (where the component is currently installed) is offline |
Switch dynamic allocation |
