Subject [jira] [Created] (KAFKA-6288) Broken symlink interrupts scanning the plugin path
Date Fri, 01 Dec 2017 02:07:00 GMT

---------------------------------

             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.

Example of error message:
