-------------------------------------
Summary: Improve Response Errors Logging
Key: KAFKA-4374
URL: https://issues.apache.org/jira/browse/KAFKA-4374
Project: Kafka
Issue Type: Bug
Components: clients
Affects Versions: 0.10.0.1
Reporter: Jesse Anderson
Priority: Minor
When NetworkClient.java gets a response error, it runs:
{code}
if (response.errors().size() > 0) {
log.warn("Error while fetching metadata with correlation id {}
: {}", header.correlationId(), response.errors());
}
{code}
Logging that at warn level and saying there is an error, is confusing to new
people. They don't see it was a warn and not error level. They just see that it
says "Error while...".
Maybe it should be something like "The metadata response from the cluster
reported a recoverable issue..."
