> We already have KAFKA-1756 filed to more completely address this issue, but
> it is waiting for some other major changes to configs to completely protect
> users from this problem.
> This JIRA should address the low hanging fruit to at least warn users of the
> potential problems. Currently the only warning is in our documentation.
> 1. Generate a warning in the kafka-topics.sh tool when they change this
> setting on a topic to be larger than the default. This needs to be very
> obvious in the output.
> 2. Currently, the broker's replica fetcher isn't logging any useful error
> messages when replication can't succeed because a message size is too large.
> Logging an error here would allow users that get into a bad state to find out
> why it is happening more easily. (Consumers should already be logging a
> useful error message.)
