Shutdown

To properly shutdown a Dremio cluster please use the following instructions:

If using a Yarn deployment

1. Navigate to the Admin -> Provisioning screen in the Dremio UI and click the Stop Cluster button. This will bring down all Dremio executors (running as Yarn containers) in the Hadoop cluster.
2. Manually shutdown all the coordinators (EXCEPT for the master coordinator, if it is a separate node) one-at-a-time waiting for each one to successfully complete before moving on to the next one. Use the appropriate shutdown command (shutdown command list below) as per your deployment.
3. Manually shutdown the master coordinator last.

If using a non-Yarn deployment:

1. Manually shutdown all the executors one-at-a-time waiting for each one to successfully complete before moving on to the next one. Use the appropriate shutdown command (shutdown command list below) as per your deployment.
2. Manually shutdown all the coordinators (EXCEPT for the master coordinator, if it is a separate node) one-at-a-time waiting for each one to successfully complete before moving on to the next one.
3. Manually shutdown the master coordinator last.

Shutdown Commands:

RPM: service dremio stop

TAR: <DREMIO-HOME>/bin/dremio stop

Startup

To properly startup a Dremio cluster please use the following instructions:

If using a Yarn deployment

1. Manually startup the master coordinator first. Use the appropriate startup command (startup command list below) as per your deployment.
2. Manually startup the remaining coordinators one-at-a-time waiting for each one to successfully complete before moving on to the next one.
3. Navigate to the Admin -> Provisioning screen in the Dremio UI and click the Start Cluster button. This will bring up all Dremio executors (running as Yarn containers) in the Hadoop cluster.

If using a non-Yarn deployment:

1. Manually startup the master coordinator first. Use the appropriate startup command (startup command list below) as per your deployment.
2. Manually startup the remaining coordinators one-at-a-time waiting for each one to successfully complete before moving on to the next one.
3. Manually startup all the executors one-at-a-time waiting for each one to successfully complete before moving on to the next one.

Startup Commands:

RPM: service dremio start

TAR: <DREMIO-HOME>/bin/dremio start

Status

To view the current status of your Dremio cluster please use the following instructions:

Status Commands:

RPM: service dremio status

TAR: <DREMIO-HOME>/bin/dremio status

If using a Yarn deployment you may also view the current status of your Dremio cluster in the Admin -> Node Activity screen in the Dremio UI.
