Connect to kerberos authenticated schema registry using Python Library python-schema-registry-client

Pr1 — Tue, 09 Feb 2021 14:46:52 GMT

Hello ,

We have one use case where we need to connect to HDF schema registry using Python Library .

We have installed python-schema-registry-client library.

But Schema registry URL is kerberos authenticated URL so couldn't connect with

below code

from schema_registry.client import SchemaRegistryClient, schema

client = SchemaRegistryClient(url="http://127.0.0.1:8081")

Getting Authentication error 401.

Is there any extra arguments or methods to get connect to Schema registry using python library?

Thanks and Regards

Cloudera Schema Registry is rarely on 8081

It is usually on port 9090.

Which version are you using? Which form factor? Public Cloud? On-Premise?

Check out the swagger rest docs

That Python is for the Confluent Schema Registry.

I was able to connect, but Confluent supports their own Avro schema format.

This was my example and it worked:

from schema_registry.client import SchemaRegistryClient, schema

client = SchemaRegistryClient(url="http://myclouderasr.com:7788")

print( client.get_schema('weatherny') )

This library doesn't seem to support logins or security.

Thanks Spann for useful links and information about python-schema-registry-client library.

So now I can see one of possible way to connect to kerberos Schema registry URL through python is requests_kerberos library.

Thanks and Regards
