Hello, I set the controller config as per the documentation. However controller is not starting up and throwing error.

controller.realtime.segment.validation.frequencyInSeconds=900
controller.broker.resource.validation.frequencyInSeconds=900

2021/02/18 14:46:44.389 ERROR [StartServiceManagerCommand] [main] Failed to start a Pinot [CONTROLLER] at 39.246 since launch

Can you provider a complete stack which will tell more context?

This is the error sorry accidentally send before adding full log

I mean… don’t you have more logs?

what’s the controller config ? did you put any config with value

[300, 900]

?

nope all I did was setting two properties

I’m wondering if you have another (duplicate) setting in the config file for either of those two values, with a setting =300, and it builds a multi-value property setting.

Indeed, the config framework of pinot appends duplicate properties

This is a good catch, we should avoid this case.

Ahh thats correct I have it defined at two places..!!! . I was somehow having kafka in mind which picks the last config.

Kudos to @Ken Krugler

Can you also create a github issue so we can track and fix this

You’re welcome - though I still owe about 50x in help that I’ve received from everyone while learning about Pinot 🙂

Thanks!
