Jason Rosenberg created KAFKA-1066:
--------------------------------------
Summary: Reduce logging on producer connection failures
Key: KAFKA-1066
URL: https://issues.apache.org/jira/browse/KAFKA-1066
Project: Kafka
Issue Type: Bug
Components: producer
Affects Versions: 0.8
Reporter: Jason Rosenberg
Assignee: Jun Rao
Below is a stack trace from a unit test, where a producer tries to send a
message, but no server is available.
The exception/message logging seems to be inordinately verbose.
I'm thinking a simple change could be to not log full stack traces for simple
things like "Connection refused", etc. Seems it would be fine to just log the
exception message in such cases.
Also, the log levels could be tuned, such that things logged as ERROR indicate
that all possible retries have been attempted, rather than having it be an
ERROR for each step of the retry/failover process. Thus, for a redundant,
clustered service, it should be considered normal that single nodes will be
unavailable (such as when we're doing a rolling restart of the cluster, etc.).
It should only be an ERROR if all brokers/all replicas are unavailable, etc.
This way, we can selectively set our log level to ERROR, and have it be useful.
This is from one of my unit tests. I am using the default retry count (3)
here, but even if I reduced that, it seems this is a crazy amount of logging.
(I've edited this to remove from each stack trace the portion of
testing/calling code, into the Producer.send() call).
Here's the code snippet that produced the logging below (and note, the server
was not available on the requested port).
KeyedMessage<Integer, T> msg = new KeyedMessage<Integer, T>(topic,
message);
producer.send(msg);
