> KIP-146: Support per-connector/per-task classloaders in Connect
> ---------------------------------------------------------------
>
> Key: KAFKA-3487
> URL: https://issues.apache.org/jira/browse/KAFKA-3487
> Project: Kafka
> Issue Type: New Feature
> Components: KafkaConnect
> Affects Versions: 0.10.0.0
> Reporter: Ewen Cheslack-Postava
> Assignee: Konstantine Karantasis
> Priority: Critical
> Labels: needs-kip
> Fix For: 0.11.0.0

>
> Currently we just use the default ClassLoader in Connect. However, this
> limits how we can compatibly load conflicting connector plugins. Ideally we
> would use a separate class loader per connector/task that is instantiated to
> avoid potential conflicts.
> Note that this also opens up options for other ways to provide jars to
> instantiate connectors. For example, Spark uses this to dynamically publish
> classes defined in the REPL and load them via URL:
> https://ardoris.wordpress.com/2014/03/30/how-spark-does-class-loading/ But
> much simpler examples (include URL in the connector class instead of just
> class name) are also possible and could be a nice way to more support dynamic
> sets of connectors, multiple versions of the same connector, etc.
