Subject [jira] [Created] (KAFKA-4827) Kafka connect: Escape special characters in connector name
Date Wed, 01 Mar 2017 18:32:45 GMT
Aymeric Bouvet created KAFKA-4827:
-------------------------------------

             Summary: Kafka connect: Escape special characters in connector name
                 Key: KAFKA-4827
                 URL: https://issues.apache.org/jira/browse/KAFKA-4827
             Project: Kafka
          Issue Type: Bug
          Components: KafkaConnect
    Affects Versions: 0.10.1.0
            Reporter: Aymeric Bouvet
            Priority: Minor


When creating a connector, if the connector name (and possibly other properties) end with
a carriage return, kafka-connect will create the config but report error

cat << EOF > file-connector
.json
{
  "name": "file-connector\r",
  "config": {
    "topic": "kafka-connect-logs\r",
    "tasks.max": "1",
    "file": "/var/log/ansible-confluent/connect.log",
    "connector.class": "org.apache.kafka.connect.file.FileStreamSourceConnector"
  }
}
EOF
curl -X POST -H "Content-Type: application/json" -H "Accept: application/json" -d @file-connector
.json localhost:8083/connectors 

returns an error 500 <Request Failed> and log the following
