Problem starting Cruise Control
Closed this issue · 5 comments
How much of the sample config needs to be changed? When the cruise-control pod starts it complains about the config entries like so
542 [ main] WARN lients.consumer.ConsumerConfig - The configuration 'sample.store.class' was supplied but isn't a known config.
542 [ main] WARN lients.consumer.ConsumerConfig - The configuration 'default.goals' was supplied but isn't a known config.
however 'default.goals' is a required entry. when commenting it out, it rightfully complains about a missing required entry.
I'm not sure how to fix this
Based on #218 (comment) it looks like those warnings have been there from the start. Also see #250 about how it's sometimes non-obvious what Cruise Control's logs mean. Maybe your setup is working?
it crashes right after
547 [ main] INFO .apache.kafka.clients.Metadata - Cluster ID: 5YMUrVGkTXe_Okw-X22Cbg

should have included that first
Because Cruise Control 2 was at an early stage back in #218 I've kept bumping to new versions. Maybe something changed. I've triggered another build just now that should be ready in an hour or so. We could try that one, and after that troubleshoot.
e113521 gets you the latest release.
I think the warnings are the result of one set of properties being used for multiple components.
That worked, thanks!
