----------------------------------
Summary: Broker.createBroker should work if json is version > 2,
but still compatible
Key: KAFKA-3100
URL: https://issues.apache.org/jira/browse/KAFKA-3100
Project: Kafka
Issue Type: Improvement
Components: core
Affects Versions: 0.9.0.0
Reporter: Ismael Juma
Assignee: Ismael Juma
Fix For: 0.9.0.1
Description from Jun:
In 0.9.0.0, the old consumer reads broker info directly from ZK and the code
throws an exception if the version in json is not 1 or 2. This old consumer
will break when we upgrade the broker json to version 3 in ZK in 0.9.1, which
will be an issue. We overlooked this issue in 0.9.0.0. The easiest fix is
probably not to check the version in ZkUtils.getBrokerInfo().
This way, as long as we are only adding new fields in broker json, we can
preserve the compatibility.
