Not log retriable exceptions as errors #5904
Conversation

Hi @mjsax, @ijuma and @hachikuji, this is really a very simple pull request, which makes troubleshooting much simpler. Could you please take a look? |
|
Hi @t3hnar I have the same problem to get to a clean error log policy and just ignored ConsumerCoordinator.class in my logging config. Which is bad because errors in ConsumerRebalanceListener may be lost. So +1 for this |
|
@bvoss no feedback yet. Looks like this PR is being ignored :( |
|
@t3hnar I didn't found a related issue. Did you open one? May this is needed. |
|
@bvoss nope, I did not. |
|
@bvoss I've just created one https://issues.apache.org/jira/browse/KAFKA-7791 |
|
@hachikuji LGTM. But this is client code, so you should merge it if you think it makes sense. |
|
@hachikuji Should we get this into 2.2 ? If yes, please have a quick look (if you thinks it makes sense--I am not 100% sure) -- it's an one-liner, so should not take long. Just pinging again because code freeze is end of the week. |
|
@mjsax @hachikuji Any updates on this? It's cluttering our error log as well. |

Background: I've spotted tons of kafka related errors in logs, after investigation I found out that those are harmless as being retried.
Hence I propose to not log retriable exceptions as errors.
Examples of what I've see in logs:
