It is defined to be mechanism-neutral: the application that uses the API need not be hardwired into using any particular SASL mechanism. Encryption solves the problem of the man in the middle (MITM) attack. The SASL section defines a listener that uses SASL_SSL on port 9092. 1.3 Quick Start PLAIN simply mean… Implements authentication using Salted Challenge Response Authentication Mechanism (SCRAM). Separate properties (eg. SCRAM can be used in situations where ZooKeeper cluster nodes are running isolated in a private network. Creating Kafka Producer in Java. Configure We use two Data Hubs, one with a Data Engineering Template, and another with a Streams Messaging template. Now, before creating a Kafka producer in java, we need to define the essential Project dependencies. You must provide JAAS configurations for all SASL authentication mechanisms. In this guide, let’s build a Spring Boot REST service which consumes … So, how do we use SASL to authenticate with such services? public static final java.lang.String SASL_KERBEROS_SERVICE_NAME_DOC See Also: Constant Field Values; SASL_KERBEROS_KINIT_CMD public static final java.lang.String SASL_KERBEROS_KINIT_CMD See Also: Constant Field Values; SASL_KERBEROS_KINIT_CMD_DOC public static final java.lang.String SASL_KERBEROS_KINIT_CMD_DOC See Also: Constant Field Values Digest-MD5). Pre-requisite: Novice skills on Apache Kafka, Kafka producers and consumers. Although, more and more applications and coming on board with SASL — for instance, Kafka. SCRAM credentials are stored centrally in ZooKeeper. Connect to CloudKarafka using Java and SASL/SCRAM-authentication - CloudKarafka/java-kafka-example may make it easier to parse the configuration. JAAS is also used for authentication of connections between Kafka and ZooKeeper. Listener using TLS encryption and, optionally, authentication using TLS client certificates. Format this list as a comma-separated list of host:port entries. SASL authentication is configured using Java Authentication and Authorization Service (JAAS). Edit the /opt/kafka/config/server.properties Kafka configuration file on all cluster nodes for the following: Download Apache Kafka  and Start Zookeeper, SASL authentication is configured using Java Authentication and Authorization Service (JAAS). now I am trying to solve some issues about kerberos. 2020-10-02 13:12:15.016 INFO 13586 --- [           main] o.a.kafka.common.utils.AppInfoParser     : Kafka version: 2.5.1, 2020-10-02 13:12:15.016 INFO 13586 --- [           main] o.a.kafka.common.utils.AppInfoParser     : Kafka commitId: 0efa8fb0f4c73d92, 2020-10-02 13:12:15.016 INFO 13586 --- [           main] o.a.kafka.common.utils.AppInfoParser     : Kafka startTimeMs: 1601624535016, 2020-10-02 13:12:15.017 INFO 13586 --- [           main] o.a.c.i.e.InternalRouteStartupManager   : Route: route2 started and consuming from: kafka://test-topic, 2020-10-02 13:12:15.017 INFO 13586 --- [mer[test-topic]] o.a.camel.component.kafka.KafkaConsumer : Subscribing test-topic-Thread 0 to topic test-topic, 2020-10-02 13:12:15.018 INFO 13586 --- [mer[test-topic]] o.a.k.clients.consumer.KafkaConsumer     : [Consumer clientId=consumer-test-consumer-group-1, groupId=test-consumer-group] Subscribed to topic(s): test-topic, 2020-10-02 13:12:15.020 INFO 13586 --- [           main] o.a.c.impl.engine.AbstractCamelContext   : Total 2 routes, of which 2 are started, 2020-10-02 13:12:15.021 INFO 13586 --- [           main] o.a.c.impl.engine.AbstractCamelContext   : Apache Camel 3.5.0 (camel) started in 0.246 seconds, 2020-10-02 13:12:15.030 INFO 13586 --- [           main] o.a.c.e.kafka.sasl.ssl.Application       : Started Application in 1.721 seconds (JVM running for 1.985), 2020-10-02 13:12:15.034 INFO 13586 --- [extShutdownHook] o.a.c.impl.engine.AbstractCamelContext   : Apache Camel 3.5.0 (camel) is shutting down, 2020-10-02 13:12:15.035 INFO 13586 --- [extShutdownHook] o.a.c.i.engine.DefaultShutdownStrategy   : Starting to graceful shutdown 2 routes (timeout 45 seconds), 2020-10-02 13:12:15.036 INFO 13586 --- [ -
