---------------------------------
Summary: 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.
Desired behavior is that the symlink is skipped and scanning the plugin path
continues.
