Hmm.. how about catching the rest of the unrecoverable errors and at least logging a meaningful error message for those, before rethrowing those as is (which is what will happen anyways if the code hits an unrecoverable error). I just think that hitting these errors due to bugs or whatever and not having a clue of what happened is kind of annoying. > On Feb. 7, 2014, 4:29 a.m., Neha Narkhede wrote: > > clients/src/main/java/org/apache/kafka/common/protocol/types/Schema.java, > > line 53 > > <https://reviews.apache.org/r/17836/diff/1/?file=479011#file479011line53> > > > > This will state the field correctly.

Understand that we don't have all the fixes now. I guess what I was saying is that it is very useful to have better error reporting in a new code base in order to understand bugs. How large is the fix to get the serde to report the right request type? - Neha ----------------------------------------------------------- This is an automatically generated e-mail.
