Greg Harris created KAFKA-9708:
----------------------------------
Summary: Connector does not prefer to use packaged classes during
configuration
Key: KAFKA-9708
URL: https://issues.apache.org/jira/browse/KAFKA-9708
Project: Kafka
Issue Type: Bug
Components: KafkaConnect
Reporter: Greg Harris
Assignee: Greg Harris
In connector tasks, classes loaded during configuration are preferentially
loaded from the PluginClassLoader since KAFKA-8819 was implemented. This same
prioritization is not currently respected in the connector itself, where the
delegating classloader is used as the context classloader. This leads to the
possibility for different versions of converters to be loaded, or different
versions of dependencies to be found when executing code in the connector vs
task.
Worker::startConnector should be changed to follow the startTask / KAFKA-8819
prioritization scheme, by activating the PluginClassLoader earlier.
