Hi Greg, I asked if there were any errors in the broker logs because the metadata request sent by the producer timed out. No messages can be sent if the producer is unable to retrieve the topic metadata. If the broker has started without errors, then the producer is unable to reach it for some reason (network setup or config problem are common reasons).
I know you said this works for 0.9.0.1, but are you sure there are is no other difference apart from the version? It may be worth trying it without using Docker. Ismael 0.10.1.0-SNAPSHOT is the broker too My procedure is the same as 0.9.0.1. I do a signed tgz build and then a local maven install. I unpack the tgz into a docker just like spotify/kafka. I run that as my server broker with ports 9092 and 2181 exposed. I link my producer code in the gist to my local maven snapshot lib (not in a Docker) Same process works for the 0.9 version Sent from my iPhone > On Apr 15, 2016, at 7:17 PM, Ismael Juma <ism...@juma.me.uk> wrote: > > Hi Greg, > > What is the broker version?
