Kafka Sink 连接器弹性云

Question

我正在尝试通过 url、用户名和密码将 kafka 连接到 Elastic 云。 我收到一个 404 错误，所以我猜这个配置不是连接到弹性集群的正确配置。 如何连接到 Elastic Cloud？

connector.class=io.confluent.connect.elasticsearch.ElasticsearchSinkConnector
type.name=_doc
connection.password=my_pass_elastic
topics=demo-topic-distributed
tasks.max=1
connection.username=my_user_elastic
connection.url=https://xxxxxxxxxxxxxxxxx.xx-xxx-x.aws.found.io:port
value.converter=org.apache.kafka.connect.json.JsonConverter
key.ignore=true
key.converter=org.apache.kafka.connect.storage.StringConverter
schema.ignore=true

我在 connection.username 和 connection.password 字段中使用的凭据与我用来从集群访问 kibana 的凭据相同。

Answer 1

指定您的 Elastic 主机的 URL 和凭据，不是 Kibana。

在 Elastic Cloud 中，您应该有一个 Copy endpoint 按钮
