i have a kerberized cluster with Kafka on it. I want to use Confluent Schema Registry with Kafka on cluster. Launching the Schema Registry from my local pc, everything works just fine. But when i uploaded it on a machine in the cluster and tried to run from it i get:
Error
ERROR Server died unexpectedly: (io.confluent.kafka.schemaregistry.rest.SchemaRegistryMain:50)
org.apache.kafka.common.KafkaException: Failed to create new KafkaAdminClient
...
Caused by: org.apache.kafka.common.KafkaException: javax.security.auth.login.LoginException: Message stream modified (41)
...
Caused by: javax.security.auth.login.LoginException: Message stream modified (41)
I also tried to run it from another machine on the cluster and i get the same result.
Schema-registry.properties

kafkastore.connection.url=master01.domain.ext:2181,master02.domain.ext:2181

EXECUTION COMMAND:
sudo bash bin/schema-registry-start ./etc/schema-registry/schema-registry.properties
QUESTIONS: Why it works in my local pc and not on a machine on cluster? What should i change?
P.S. i get the same result even trying to run the CMAK yahoo kafka-manager ( using same jaas.confing and same keytab )
