Stanislav Kozlovski commented on KAFKA-7111:
--------------------------------------------
Yes I believe it is worth it to change the log and have committed the change.
We should see it go live with version 2.0.
For the other issues like the synchronous `send()`, please do open another
issue.
PS: Thank you for your example app, it was very helpful :)

> Hi,
>
> I was using Kafka on some projects and unfortunately I had to use Debug (and
> some times even Trace) log level to see some issues. One of the most recently
> cases was:
> [https://github.com/apache/kafka/blob/trunk/clients/src/main/java/org/apache/kafka/clients/NetworkClient.java#L872]
>
> If I got the name of the broker and it is unreachable, the errors should be
> more severe than "DEBUG" level IMHO. I would at least put a INFO level for
> this case or ERROR level (which seems to fit better but I don't know the
> practices used in the project).
>
> Thank you in advance
>
