Subject Re: Upgrading from 0.10.0.1 to 0.10.1.0
Date Mon, 12 Dec 2016 08:04:44 GMT
Thanks Ewen,

I am just trying to ensure a smooth role over. So what I was able to test
so far, was 0.10.1 mirror maker with source (0.10.0.1) and target (0.10.1)
brokers. That doesn't work, even if I specify zookeepers in the consumer
config. Not work as in "comes up, does nothing, eventually throws a socket
time out".
The old version of mirror maker does work with this setup and config. I
guess I have to setup 2 new broker clusters and test new mirror maker to
start working, but it's a lot of trouble for a minor update.

tl;dr: the fine print of mirror maker update is underspecified and thus I
have a trust deficiency that the new mirror maker will work.


Cheers,
Hagen
