Configuring Dremio Services

This topic describes how to configure Dremio services depending on your deployment. Dremio services are configured in the dremio.conf file. In addition, each node in the Dremio cluster must be configure accordingly.

The Dremio services property determines whether the node is enabled with the
master-coordinator or executor role.

[info] Master-Coordinator Role

All Dremio cluster nodes with Dremio coordinator services must have the master-coordinator role enabled. A node with only the coordinator role enabled is not supported.

Coordinator Node

To configure a coordinator node with the master-coordinator role, use the following Dremio services configuration.

services: {
  coordinator.enabled: true,
  coordinator.master.enabled: true,
  executor.enabled: false
}

Executor Node

To configure a node with the executor role, use the following Dremio services configuration.

services: {
  coordinator.enabled: false,
  coordinator.master.enabled: false,
  executor.enabled: true
}
