------------------------------------
Summary: Reinstate Utils.join() method in
org.apache.kafka.common.utils
Key: KAFKA-17145
URL: https://issues.apache.org/jira/browse/KAFKA-17145
Project: Kafka
Issue Type: Bug
Components: connect
Affects Versions: 3.8.0
Reporter: Vikas Balani
h3. Description:
The Utils.join() function has been removed from the
org.apache.kafka.common.utils package. This utility function is widely used by
many connector plugins, which are now failing due to the absence of this method.
h3. Example of affected code:
The S3 Sink Connector uses this method here:
[link|https://github.com/confluentinc/kafka-connect-storage-cloud/blob/c90780dd61c6b1e11cd89c20619ac81a99aa19d5/kafka-connect-s3/src/main/java/io/confluent/connect/s3/S3SinkConnectorConfig.java#L1087]
h3. Impact:
1. Connector plugins that depend on this method are failing.
2. This change breaks backward compatibility for plugins and custom code
relying on Utils.join().
h3. Proposed Solution:
1. Partially revert https://github.com/apache/kafka/pull/15823
2. Restore the Utils.join() method in org.apache.kafka.common.utils.
3. Maintain the usage of JDK API within Apache Kafka codebase instead of
Utils.join().
4. Add a deprecation warning to Utils.join() to indicate future removal.
