Cloning Kafka repo is slow (in China).
How does the patch look ?
> Broken symlink interrupts scanning the plugin path
> --------------------------------------------------

> Key: KAFKA-6288
> URL: https://issues.apache.org/jira/browse/KAFKA-6288
> Project: Kafka
> Issue Type: Bug
> Components: KafkaConnect
> Affects Versions: 1.0.0
> Reporter: Yeva Byzek

> KAFKA-6087 introduced support for scanning relative symlinks in the plugin
> path. However, if a relative symlink points to a target that doesn't exist,
> then scanning the plugin path is interrupted. The consequence is that the
> unscanned connectors in the plugin path may effectively not be usable.
> Desired behavior is that the symlink with the non-existent target is skipped
> and scanning the plugin path continues.
> Example of error message:
> {noformat}
> [2017-11-30 20:19:26,226] ERROR Could not get listing for plugin path:
> /usr/share/java. Ignoring.
