Hi, After enabled Kerberos using Ambari, I got problem creating topics in Kafka using the kafka-topics.sh script. The topic was created, but its status is wrong without leader. It seems the topic is created with PLAINTEXT, while there is only PLAINTE…

PROBLEM DESCRIPTION When creating or deleting topics in Kafka, they cannot be authorized through the Ranger policies. The following errors are displayed while creating the topics: [ADM_xxxx@xxxx-oc-had102 ~]$ /usr/hdp/current/kafka-broker/bin/kafka-t…

根据flume官网:当kafka涉及kerberos认证: 涉及两点配置,如下: 配置一:见下实例中红色部分 配置conf实例: [root@gz237-107 conf]# cat flume_slipstream.conf a1.sources =r1 a1.sinks = k1 a1.channels = c1   # 定义source a1.sources.r1.type = avro a1.sources.r1.bind = 0.0.0.0 a1.sources.r1.port = 8…

转载请注明原创地址:http://www.cnblogs.com/dongxiao-yang/p/7131626.html kafka从0.9版本以后引入了集群安全机制,由于最近需要新搭建一套kafka集群,决定采用SASL/GSSAPI (Kerberos) 作为新集群的权限系统基础,本次新集群版本为0.10.2.0. 团队内部已有同学搭建了专门的kerberos服务器,所以省掉了自建kerberos的步骤. (1)首先是为broker每台服务器在kerber服务器生成相应的principal…

一.背景 在我们部署完kafka之后,虽然我们已经可以“肆意”的用kafka了,但是在一个大公司的实际生产环境中,kafka集群往往十分庞大,每个使用者都应该只关心自己所负责的Topic,并且对其他人所使用的Topic没有权限.这样一来可以将资源隔离开来,二来可以防止误操作. 在权限控制之前,我们必须要启用的就是用户认证,没有用户,自然没有权限一说了. 二.kafka启用kerberos认证 2.1 在KDC中添加kafka用户,并生成keytab 新建kfaka用户 kadmin.local…

kafka的认证方式一般有如下3种: 1. SASL/GSSAPI  从版本0.9.0.0开始支持 2. SASL/PLAIN   从版本0.10.0.0开始支持 3. SASL/SCRAM-SHA-256 以及 SASL/SCRAM-SHA-512   从版本0.10.2.0开始支持 其中第一种SASL/GSSAPI的认证就是kerberos认证,对于java来说有原生的支持,但是对于python来说配置稍微麻烦一些,下面说一下具体的配置过程,confluent kafka模块底层依赖于lib…
