----------------------------------
Summary: Inconsistencies in 0.10.1 upgrade docs
Key: KAFKA-4257
URL: https://issues.apache.org/jira/browse/KAFKA-4257
Project: Kafka
Issue Type: Bug
Components: documentation
Affects Versions: 0.10.1.0
Reporter: Jeff Klukas
Priority: Minor
Fix For: 0.10.1.0
There are several inconsistencies in the 0.10.1.0 upgrade docs that make it
difficult to determine what client versions are compatible with what broker
versions.
The initial heading in the upgrade docs is "Upgrading from 0.10.0.X to
0.10.1.0", but it includes clauses about versions prior to 0.10. Is the
intention for these instructions to be valid for upgrading from brokers as far
back as 0.8? Should this section simply be called "Upgrading to 0.10.1.0"?
I cannot tell from the docs whether I can upgrade to 0.10.1.0 clients on top of
0.10.0.X brokers. In particular, step 5 of the upgrade instructions mentions
"Once all consumers have been upgraded to 0.10.0". Should that read 0.10.1, or
is the intention here truly that clients on 9.X or below need to be at version
0.10.0.0 at a minimum?
