[Hawkular-dev] Could not connect to Cassandra ... - does it have to be a WARN with a stack trace?

[Michael Burman]

Hi,

And how would you distinguish between real warning and incorrect one? This message is not printed when Hawkular-Metrics starts standalone andshould not be removed. This is a container issue in Hawkular and should be fixed there (so that no such error happens) instead of breaking the logging in metrics. Most likely this happens with embedded-cassandra I guess?

Hi *,

There are several occurrences of this in every Hawkular start log:

WARN  [org.hawkular.metrics.api.jaxrs.MetricsServiceLifecycle] 
(metricsservice-lifecycle-thread) Could not connect to Cassandra cluster 
- assuming its not up yet: 
com.datastax.driver.core.exceptions.NoHostAvailableException: All 
host(s) tried for query failed (tried: /127.0.0.1:9042 
(com.datastax.driver.core.TransportException: [/127.0.0.1:9042] Cannot 
connect))

plus the stack trace.

So given that this happens during every HK startup, could we not 
classify it as normal and change it to INFO without the stack trace?

I am ready to prepare a PR unless somebody raises a hand against that.

Thanks,

Peter
