Running 0.8 against 0.7 data and zk

This JIRA has a patch but I thought we already did something like this:
https://issues.apache.org/jira/browse/KAFKA-686

Am I just confused?

That sounds like a a future frequently asked question. I wonder if we
should try to add some heuristic to check the format of the log and/or zk
to error out more gracefully?

Folks should we do this for 0.8?

No. If you point an 0.8 broker to a ZK with 0.7 layout, it will still hit
some weird exception, maybe not exactly the same as specified in the jira.

Thanks,
