Hello!! I’m building an application on Apache Pinot and I need to customize a few features, but some errors are happening. I think the controller can’t associate to the configurations. I’m receiving null results. The following configurations were executed, leading to this problem: The file pinot-controller.conf has this configuration:

pinot.service.role=CONTROLLER

controller.port=9001

controller.zk.str=localhost:2181

controller.access.protocols.http.port=9001

pinot.cluster.name=MyClusterName

controller.vip.host=localhost

controller.vip.port=9001

controller.data.dir=/tmp/pinot/data/controller

controller.helix.cluster.name=MyClusterName

pinot.set.instance.id.to.hostname=true

controller.admin.access.control.principals=admin,user

controller.admin.access.control.principals.user.password=admin

controller.admin.access.control.principals.user.permissions=READ

controller.admin.access.control.principals.admin.password=admin

controller.admin.access.control.factory.class=org.apache.pinot.controller.api.access.BasicAuthAccessControlFactory

I’m executing with Docker compose and the following call is the one that I use to iniciate the controller:

StartController -configFileName /tmp/conf/pinot-controller.conf

The following mistake appears:

2022/06/01 154850.463 INFO [StartControllerCommand] [main] Executing command: StartController -configFileName /tmp/conf/pinot-controller.conf

pinot-controller | 2022/06/01 154850.541 ERROR [StartControllerCommand] [main] Caught exception while starting controller, exiting.

Does that mistake happen due some account configuration problem or is it some sort of internal bug from Apache Pinot?
