Hey everyone!
One of my Mirrormakers is exiting with the following error:
[2015-09-18 11:27:35,591] FATAL [mirrormaker-consumer-0] Stream
unexpectedly exited. (kafka.tools.MirrorMaker$ConsumerThread)
kafka.message.InvalidMessageException: Message is corrupt (stored crc =

The same topic has been mirrored to another DC without a problem.
A few questions arise:
* Why could the other DC mirror the topic successfully?
* Why is the MM not failing for the message, but carrying on?
* What can I do now to carry on consuming with this MM?
* How can I automate the answers to the above?
My MM currently also does not want to write a log, although I passed on:
KAFKA_LOG4J_OPTS="-Dlog4j.configuration=file:${KAFKA_CONFIG}/mirror/log4j.properties"
Any clues why I don't get any log output? (I got the error from running
MM interactive)
Thanks
Jörg
