Shutdown
To properly shutdown a Dremio cluster please use the following instructions:
If using a Yarn deployment
- Navigate to the
Admin -> Provisioning
screen in the Dremio UI and click theStop Cluster
button. This will bring down all Dremio executors (running as Yarn containers) in the Hadoop cluster. - 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.
- Manually shutdown the master coordinator last.
If using a non-Yarn deployment:
- 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.
- 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.
- 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
- Manually startup the master coordinator first. Use the appropriate startup command (startup command list below) as per your deployment.
- Manually startup the remaining coordinators one-at-a-time waiting for each one to successfully complete before moving on to the next one.
- Navigate to the
Admin -> Provisioning
screen in the Dremio UI and click theStart Cluster
button. This will bring up all Dremio executors (running as Yarn containers) in the Hadoop cluster.
If using a non-Yarn deployment:
- Manually startup the master coordinator first. Use the appropriate startup command (startup command list below) as per your deployment.
- Manually startup the remaining coordinators one-at-a-time waiting for each one to successfully complete before moving on to the next one.
- 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
