Hi Frank, Which version of kafka are you running? The line numbers in the stack trace don't match up with what i am seeing on 0.10.1 or on trunk.
FYI - I created a JIRA for this here: https://issues.apache.org/jira/browse/KAFKA-4311 Thanks, Damian On Tue, 18 Oct 2016 at 15:52 Damian Guy <damian....@gmail.com> wrote: > Also, it'd be great if you could share your streams topology. > > Thanks, > Damian > > On Tue, 18 Oct 2016 at 15:48 Damian Guy <damian....@gmail.com> wrote: > > Hi Frank, > > Are you able to reproduce this?
