--------------------------------------------
Summary: Warn users if they change max.message.bytes that they
also need to update broker and consumer settings
Key: KAFKA-2338
URL: https://issues.apache.org/jira/browse/KAFKA-2338
Project: Kafka
Issue Type: Bug
Components: core
Affects Versions: 0.8.2.1
Reporter: Ewen Cheslack-Postava
Fix For: 0.8.3
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.)
