Ewen Cheslack-Postava commented on KAFKA-4915:
----------------------------------------------
[~dernasherbrezon] No, this is actually great, I just wasn't seeing it! Unless
you have structured logging output that makes it easy to filter this stuff,
messages like that can definitely be annoying noise.
I just did a quick grep for possible similar issues:
{code}
git grep log[.][^e] | grep -i error
{code}
and although some of the results are false positives, there are quite a few
warn and debug level messages that contain the word error. A broader patch to
clean these up would be great. Any interest in submitting a PR? I'd be happy to
get it committed.
