MoP and KoP cannot be used together about mop HOT 11 CLOSED

Hi, Could you give more description about your issue?
I have tried to set the above interceptor, it's working in my local.

from mop.

KoP needs to be added after version 2.80

brokerentrymetadatainterceptors = org. Apache. Pulsar. Common. Intercept. Appendindexmetadatainterceptor

KoP works normally, but when I add MoP, the mqtt client can publish messages normally, but cannot subscribe to messages

I think you can provide more info for this, some like your topic, qos, etc..

And you are use mqtt consumer and mqtt producer, right?

mqtt producer --> mqtt connsumer

from mop.

When I use the above configuration, remove it

brokerEntryMetadataInterceptors=org.apache.pulsar.common.intercept.AppendIndexMetadataInterceptor

MQTT clients can publish and subscribe to messages


but, Kafka cannot publish and subscribe messages .

If I modify the configuration as above add it
brokerEntryMetadataInterceptors=org.apache.pulsar.common.intercept.AppendIndexMetadataInterceptor
Kafka client can publish and subscribe messages.
but the mqtt client can publish messages normally, cannot subscribe to messages

The above is the detailed configuration and information.
I'm using a local build nar.
commit id is f6602d8
@Technoboy-

from mop.

I tried to update the latest version of the mop code and found that the MQTT client could not subscribe to the messages with or without the addition of brokerEntryMetadataInterceptors=org.apache.pulsar.common.intercept.AppendIndexMetadataInterceptor
to the configuration file

from mop.

@fanyouyong0526 Which Pulsar version are you using, please make sure the Pulsar version is the same as the mop plugin version.

from mop.

@Technoboy- Looks we need to add an integration test in the streamnative-tests to make sure MoP can work with KoP together.

from mop.

pulsar version：2.8.0
mop：A locally built version，commitid is f6602d8

from mop.

Could you try 2.8.1? It's because Commands#parseMessageMetadata didn't skip the BrokerEntryMetadata in 2.8.0, but apache/pulsar#10968 added the skipBrokerEntryMetadataIfExist call in parseMessageMetadata. After that, parseMessageMetadata should work.

from mop.

Please upgrade pulsar to 2.8.1.
