Hello, We have kerberosed Hadoop Cluster.
Metron is trying to access all the Kafka topics (ir-respective of Kafka topics which needed for Metron) Since it does not have access to all topics, in UI Kafka related infos are not displayed. For Ex : Kafka has some other topics like (checking123) Metron need authorization for those topic as well. 2018-01-10T11:17:39.576 DEBUG [org.springframework.web.servlet.mvc.method.annotation.HttpEntityMethodProcessor] - Written [{timestamp=Wed Jan 10 11:17:39 AEDT 2018, status=500, error=Internal Server Error, exception=org.apache.kafka.common.errors.TopicAuthorizationException, message=Not authorized to access topics: [checking123], path=/api/v1/kafka/topic/snort}] as "application/json" using [org.springframework.http.converter.json.MappingJackson2HttpMessageConverter@ab327c ] Can Metron Rest restrict access only to those topics which is needed for the same, thanks Regards, Prakash R
