Most of the properties in Pinot are set in Zookeeper via Helix. However, you can also set properties in controller.conf file. You can specify the path to config file at the startup time as follows -
bin/pinot-admin.sh StartController -configFileName /path/to/controller.conf
Controller.conf can have the following properties -
| Property | Default | Description |
|---|---|---|
| controller.vip.host | same as controller.host |
The VIP hostname used to set the download URL for segments |
