Confluent 5.4.0 ElasticSearch Sink 连接器中没有连接器类型错误

Question

我在我的 Kafka 主题中引入了来自 Twitter 源连接器的数据 "demo-twitter-status"

我想将其下沉到 ElasticSearch 中。我做的连接器是这样的：

curl -k -X POST  http://xxxxxxxxxx:8083/connectors -H "Content-Type: application/json" --data '{
  "name":"sink-elasticsearch-connector1",
  "config":{
    "tasks.max": "2",
    "topics":"demo-twitter-status",
    "key.converter":"org.apache.kafka.connect.json.JsonConverter",
    "key.converter.schema.enable":"true",
    "value.converter":"org.apache.kafka.connect.json.JsonConverter",
    "value.converter.schema.enable":"true",
    "connection.url":"http://xxxxxxxx:9200",
    "type.name":"kafka-connect",
    "key.ignore":"true"
    }
}'

这是错误的：

{
  "error_code": 400,
  "message": "Connector config {type.name=kafka-connect, key.converter.schema.enable=true, tasks.max=2, topics=demo-twitter-status,
   value.converter.schema.enable=true, name=sink-elasticsearch-connector1, value.converter=org.apache.kafka.connect.json.JsonConverter,
   connection.url=http://===========:9200, key.ignore=true, key.converter=org.apache.kafka.connect.json.JsonConverter}
   contains no connector type"
}

我也用过"type.name":"kafkaconnect" and "type.name":"_doc"，但还是出现同样的错误。

任何人都可以帮我更正我的连接器。提前致谢！！！

版本如下：

合流 5.4.0

弹性搜索 7.6

PS：confluent 文档说 confluent 5.4.0

支持 7.x

原因如您的错误所示：

Connector config …   contains no connector type

您需要指定 connector.class 以便 Kafka Connect 知道使用 Elasticsearch 接收器连接器。

尝试

curl -k -X POST  http://xxxxxxxxxx:8083/connectors -H "Content-Type: application/json" --data '{
  "name":"sink-elasticsearch-connector1",
  "config":{
    "connector.class":  "io.confluent.connect.elasticsearch.ElasticsearchSinkConnector",
    "tasks.max": "2",
    "topics":"demo-twitter-status",
    "key.converter":"org.apache.kafka.connect.json.JsonConverter",
    "key.converter.schema.enable":"true",
    "value.converter":"org.apache.kafka.connect.json.JsonConverter",
    "value.converter.schema.enable":"true",
    "connection.url":"http://xxxxxxxx:9200",
    "type.name":"kafka-connect",
    "key.ignore":"true"
    }
}'
