问题：

NiFi不会开始与动物园管理员Kerberos配置

易招
2023-03-14

我目前在让NiFi和Zookeeper使用Kerberos进行身份验证时遇到了一些问题。任何帮助都将不胜感激。

当我尝试用Kerberos配置启动NiFI时，它只是在启动过程中关闭。

我正在使用外部ZooGuard集群（不是嵌入式集群）。根据NiFi管理指南，我已将以下内容添加到我的配置文件中：

$NIFI\U HOME/conf/bootstrap。形态：

java.arg.15=-Djava.security.auth.login.config=/opt/nifi/conf/zookeeper-jaas.conf

$NIFI_HOME/conf/nifi.properties：

nifi.zookeeper.auth.type=sasl
nifi.zookeeper.kerberos.removeHostFromPrincipal=true
nifi.zookeeper.kerberos.removeRealmFromPrincipal=true

$NIFI\U HOME/conf/zookeeper jaas。形态：

Client {
    com.sun.security.auth.module.Krb5LoginModule required
    useKeyTab=true
    keyTab="/opt/nifi/conf/nifi.keytab"
    storeKey=true
    useTicketCache=false
    principal="HTTP/nifi-2.nifi.nifi4.svc.cluster.local@MYDOMAIN.NET";
    };

我也使用初始化keytab：

kinit -kt /opt/nifi/conf/nifi.keytab HTTP/nifi-2.nifi.nifi4.svc.cluster.local@MYDOMAIN.NET

当我启动NiFi时，我在它关闭之前得到以下堆栈跟踪：

如果我删除Kerberos配置，那么NiFi将运行得很好（尽管没有使用Kerberised Zookeeper）。我尝试过用一个全新的动物园管理员来运行这个程序，以防与以前的非kerberised节点发生某种冲突，但运气不佳。

对NiFi/Zookeeper有更多了解的人能帮我理解这个错误吗？

事先非常感谢，

您仍然需要在nifi中设置kerberos服务主体。属性：

nifi.kerberos.service.principal

管理指南中关于ZK客户端的留档应该更新，但它假设NiFi本身已经“kerberated”，这将设置服务主体。

    分布式 Apache HBase 安装依赖于正在运行的 ZooKeeper 集群。所有参与节点和客户端都需要能够访问正在运行的 ZooKeeper 集合。 Apache HBase 默认为您管理 ZooKeeper“集群”。它将启动和停止 ZooKeeper 集合作为 HBase 启动/停止过程的一部分。您还可以独立于 HBase 管理 ZooKeeper 集合，只需将 HBase 指向它应该使用

  • 动物园管理员出错

    我正在为Storm开发代码，这是开发人员的一个示例。我的问题是，当您从IDE Eclipse运行此代码时，不会建立Storm和ZooKeer之间的连接。ZooKeer在2181中运行，也设置在storm.yaml. 我的例外是： 有什么想法或程序要执行吗？是否从配置代码中传递？和我一样？
