Ceph BucketNotifications不会将消息推送到Kafka

Question

我有一个ceph测试群集，其中有三个节点，并且第一个节点上安装了radosgw。ceph版本为14.2.6 （f0aa067ac7a02ee46ea48aa26c6e298b5ea272e9）nautilus（稳定）

# cat /etc/ceph/ceph.conf
[global]
fsid = a204e3b5-b0e1-4598-aadc-f46011b562f0

mon_initial_members = ceph-test-01, ceph-test-02, ceph-test-03
mon_host = 172.19.19.252,172.19.19.251,172.19.19.244

auth_cluster_required = cephx
auth_service_required = cephx
auth_client_required = cephx

public network = 172.19.19.0/24

rgw_frontends = beast port=80

和Apache Kafka代理用于接收消息。

我已经根据官方CEPH文档创建了一个主题：

（[https://docs.ceph.com/docs/master/radosgw/notifications/）。

POST http://ceph-test-01/?Action=CreateTopic&Name=bucketnotifications&push-endpoint=kafka://kafka-test-01:9092 with S3 credentials
Response:
<CreateTopicResponse xmlns="https://sns.amazonaws.com/doc/2010-03-31/">
    <CreateTopicResult>
        <TopicArn>arn:aws:sns:us::bucketnotifications</TopicArn>
    </CreateTopicResult>
    <ResponseMetadata>
        <RequestId>14804357-9c29-437d-9789-c127e1c13d23.44108.275</RequestId>
    </ResponseMetadata>
</CreateTopicResponse>

我创建了一个名为new-bucket的存储桶，并检查了其配置：

GET http://ceph-test-01/new-bucket?notification
Response:
<NotificationConfiguration>
    <TopicConfiguration>
        <Id>bucketnotifications</Id>
        <Topic>arn:aws:sns:us::bucketnotifications</Topic>
        <Event>s3:ObjectCreated:*</Event>
        <Event>s3:ObjectRemoved:*</Event>
    </TopicConfiguration>
</NotificationConfiguration>

当我向存储桶添加或删除文件时，ceph不会将通知推送到Apache Kafka主题。 Radosgw日志（打开调试模式）包含以下字符串：

2020-03-04 10:58:00.533 7f29a8da3700 20 notification: 'bucketnotifications' on topic: 'bucketnotifications' and bucket: 'new-bucket' (unique topic: 'bucketnotifications') apply to event of type: 's3:ObjectCreated:Put'
2020-03-04 10:58:00.533 7f29a8da3700  1 ERROR: failed to create push endpoint: kafka://kafka-test-01:9092 due to: pubsub endpoint configuration error: unknown schema in: kafka://kafka-test-01:9092
2020-03-04 10:58:00.533 7f29a8da3700  5 req 188 0.248s s3:put_obj WARNING: publishing notification failed, with error: -22

但是Apache Kafka没有创建新主题。

似乎在nautilus发行版中存在一个错误，kafka模式无法检查。您可以升级到支持此架构的15.2.0版本，或等待nautilus上的错误修复更新。
