我正在使用以下docker编写代码段：

connect:
    image: confluentinc/cp-kafka-connect:latest
    hostname: connect
    container_name: connect
    depends_on:
      - zookeeper
      - kafka
    ports:
      - "8083:8083"
    environment:
      CONNECT_BOOTSTRAP_SERVERS: 'kafka:9092'
      CONNECT_REST_ADVERTISED_HOST_NAME: connect
      CONNECT_GROUP_ID: compose-connect-group
      CONNECT_CONFIG_STORAGE_TOPIC: docker-connect-configs
      CONNECT_CONFIG_STORAGE_REPLICATION_FACTOR: 1
      CONNECT_OFFSET_FLUSH_INTERVAL_MS: 10000
      CONNECT_OFFSET_STORAGE_TOPIC: docker-connect-offsets
      CONNECT_OFFSET_STORAGE_REPLICATION_FACTOR: 1
      CONNECT_STATUS_STORAGE_TOPIC: docker-connect-status
      CONNECT_STATUS_STORAGE_REPLICATION_FACTOR: 1
      CONNECT_KEY_CONVERTER: org.apache.kafka.connect.json.JsonConverter
      CONNECT_VALUE_CONVERTER: org.apache.kafka.connect.json.JsonConverter
      CONNECT_INTERNAL_KEY_CONVERTER: org.apache.kafka.connect.json.JsonConverter
      CONNECT_INTERNAL_VALUE_CONVERTER: org.apache.kafka.connect.json.JsonConverter
      CONNECT_PLUGIN_PATH: /usr/share/java
      CONNECT_ZOOKEEPER_CONNECT: 'zookeeper:2181'

容器似乎启动得很好，但是当我尝试通过connect container rest api添加hdfs sink连接时：

curl -s -X POST -H 'Content-Type: application/json' --data \
@confluent_hdfs.json http://localhost:8083/connectors

其中合流的\u hdfs.json文件包含：

{
  "name": "hdfs-sink",
  "config": {
    "connector.class": "io.confluent.connect.hdfs.HdfsSinkConnector",
    "tasks.max": "1",
    "topics": "test",
    "hdfs.url": "hdfs://localhost:9000",
    "flush.size": "1000",
    "name": "hdfs-sink"
  }
}

我得到一个500 http响应。检查连接器容器的日志显示：

WARN /connectors (org.eclipse.jetty.server.HttpChannel)
javax.servlet.ServletException: javax.servlet.ServletException:
org.glassfish.jersey.server.ContainerException: java.lang.NoClassDefFoundError: 
io/confluent/connect/hdfs/HdfsSinkConnectorConfig

通过查看此问题，我看到以下帖子：
https://github.com/confluentinc/kafka-connect-hdfs/issues/273
这表明插件路径是错误的。然而，据我所知，我已经将其正确地设置为/usr/share/java，并且我还看到了本文提到的正确配置的符号链接。
此外，在执行请求时：

curl http://localhost:8083/connector-plugins

我看到以下回应：

[
{"class":"io.confluent.connect.hdfs.HdfsSinkConnector","type":"sink","version":"4.1.1"},
{"class":"io.confluent.connect.hdfs.tools.SchemaSourceConnector","type":"source","version":"1.1.1-cp1"},
{"class":"org.apache.kafka.connect.file.FileStreamSinkConnector","type":"sink","version":"1.1.1-cp1"},
{"class":"org.apache.kafka.connect.file.FileStreamSourceConnector","type":"source","version":"1.1.1-cp1"}
]

所以我真的不确定我是在撰写文件中遗漏了什么，还是在这里遗漏了什么？
