Abris not working when used with confluent schema registry over basic auth (found on dataproc) #364
Description
This is an issue with confluent-schema-registry-client though but getting extended to Abris. The issue is, when schema registry is being used with basic auth over a confluent instance, it is showing 401 while fetching schema from confluent (incase of dataproc cluster over a private VPN). One can not just pass credentials like following:
AbrisConfig.fromConfluentAvro.downloadReaderSchemaByLatestVersion
.andTopicNameStrategy(getTopic)
.usingSchemaRegistry(
Map(
AbrisConfig.SCHEMA_REGISTRY_URL -> Configuration.schemaRegistryUrl,
SchemaRegistryClientConfig.BASIC_AUTH_CREDENTIALS_SOURCE -> "USER_INFO",
SchemaRegistryClientConfig.USER_INFO_CONFIG -> s"${Configuration.schemaRegistryUsername}:${Configuration.schemaRegistryPassword}"
)
)
instead confluent can give you schema if used with a rest service created and passed through. e.g.
val restService = new RestService(urls)
val provider = new UserInfoCredentialProvider()
provider.configure(configs.asJava)
restService.setBasicAuthCredentialProvider(provider)
new CachedSchemaRegistryClient(restService, maxSchemaObject)
The current implementation of this is not allowing to use restService based constructor with CachedSchemaRegistryClient, so I have tried changing Abris code and made a separate jar with above change. Raising a PR to add this feature.
