------------------------------------
Summary: Make zookeeper.connect optional for Kafka connectors
Key: FLINK-16125
URL: https://issues.apache.org/jira/browse/FLINK-16125
Project: Flink
Issue Type: Improvement
Components: Connectors / Kafka
Affects Versions: 1.10.0
Reporter: Jiangjie Qin
FLINK-14649 accidentally changed the connector option {{zookeeper.connect}}
from optional to required for all the Kafka connector versions, while it is
only required for 0.8.
The fix would be make it optional again. This does mean that people who are
using Kafka 0.8 might miss this option and get an error from Kafka code instead
of Flink code, but given that Kafka 0.8 probably has a small user base now and
users will still get an error. I think it is fine.
