The operation failed. Message: Peer indicated failure: Problem with callback handler

i tried with all possible scenarios 

with super users, kafka all users and i tried with kafka super.users setting on cloudera,

also add all usernames in sentry.service.admin.group and sentry.service.allow.connect

[#2]

It seems that you Sentry service is not aware of the Kafka brokers and fails to connect to the service.

You should check the following things:

• Check the property "Sentry Service" in your Kafka service configuration and ensure that the correct Sentry service is selected.
• Ensure the node from where you're running the kafka-sentry command has a Kafka Gateway role assigned to it.

After making the needed corrections, restart the stale services, deploy client configuration and try again.

Regards,

André

Hi Araujo,

still same error.

yes i verified that below are the my configs and yes i assigned Kafka Gateway role as well.

[#4]

Do you have multiple Kafka and Sentry services on your cluster? Just wondering due to the numbering of those services (KAFKA-4 and SENTRY-2)?

[#5 · Accepted solution]

yes we have multiple Kafka clusters,

Issue was fixed.

solution:-

my username added with Caps on "sentry.service.allow.connect"

earlier i added with all small.
