I'm using 0.82beta and I'm trying to push data with the mirrormaker tool
from several remote sites to two datacenters. I'm testing this from a node
containing zk, broker and mirrormaker and the data is pushed to a "normal"
cluster. 3 zk and 4 brokers with replication.
While the configuration seems straight forward things are a bit shaky.
First, if something goes wrong on either consumer or producer side it stops
transmitting data without dying which makes it harder to run under a
supervisor (upstart in my case)
I start pushing data to site 02 and mirrormaker pushes it to my datacenter
- so far all good...
But, when I run. (on my remote site)
kafka-consumer-offset-checker.sh
--group mirrormaker.from.site_02.to.site_ktv --zookeeper 192.168.0.106

Since I can push data between my sites something is working but what can be
the case for NotCoordinatorForConsumerException on a single node cluster?
Finally the __consumer_offsets topic should probably be masked out from
mirroring without using whitelists or blacklists
