Subject [jira] [Commented] (KAFKA-2526) Console Producer / Consumer's serde config is not working
Date Mon, 07 Aug 2017 15:16:01 GMT

    [ https://issues.apache.org/jira/browse/KAFKA-2526?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16116726#comment-16116726

Ewen Cheslack-Postava commented on KAFKA-2526:
----------------------------------------------

[~ardahal] Yeah, I think the scope of the bug is just unclear. Adding better errors would
be a useful short-term stopgap solution (I think you just get a cast exception or something
like that if you try to set these to something besides ByteArraySerializer, but I haven't
double checked). The longer term solution with a KIP is obviously a lot more involved, but
you should feel free to work on it; it would be a useful improvement. Since there would be
two separate steps, you'd probably want to either file a separate JIRA for the better error
messages and leave this one to the KIP or just file that fix as a MINOR PR.

> Although in the console producer one can specify the key value serializer, they are actually
not used since 1) it always serialize the input string as String.getBytes (hence always pre-assume
the string serializer) and 2) it is actually only passed into the old producer. The same issues
exist in console consumer.
> In addition the configs in the console producer is messy: we have 1) some config values
exposed as cmd parameters, and 2) some config values in --producer-property and 3) some in
--property.
> It will be great to clean the configs up in both console producer and consumer, and put
them into a single --property parameter which could possibly take a file to reading in property
values as well, and only leave --new-producer as the other command line parameter.
