Ricky Saltzer created KAFKA-1664:
------------------------------------

             Summary: Kafka does not properly parse multiple ZK nodes with non-root chroot
                 Key: KAFKA-1664
                 URL: https://issues.apache.org/jira/browse/KAFKA-1664
             Project: Kafka
          Issue Type: Bug
          Components: clients
            Reporter: Ricky Saltzer
            Priority: Blocker


When using a non-root ZK directory for Kafka, if you specify multiple ZK servers, Kafka does
not seem to properly parse the connection string.
