Apache Nifi 简明教程
Apache NiFi - Administration
Apache NiFi 为 Ambari、Zookeeper 等多个工具提供支持，以用于管理目的。NiFi 还在 nifi.properties 文件中提供了配置，以便为管理员设置 HTTPS 和其他内容。
Apache NiFi offers support to multiple tools like ambari, zookeeper for administration purposes. NiFi also provides configuration in nifi.properties file to set up HTTPS and other things for administrators.
zookeeper
NiFi 本身不处理群集中的投票过程。这意味着创建群集时，所有节点都是主节点和协调器。因此，Zookeeper 被配置为管理主节点和协调器的投票。nifi.properties 文件包含一些用于设置 Zookeeper 的属性。
NiFi itself does not handle voting process in cluster. This means when a cluster is created, all the nodes are primary and coordinator. So, zookeeper is configured to manage the voting of primary node and coordinator. The nifi.properties file contains some properties to setup zookeeper.

Enable HTTPS
如要通过 HTTPS 使用 NiFi，管理员必须生成密钥库和信任库，并在 nifi.properties 文件中设置一些属性。TLS 工具包可用于生成启用 Apache NiFi 中 HTTPS 所需的所有密钥。
To use NiFi over HTTPS, administrators have to generate keystore and truststore and set some properties in the nifi.properties file. The TLS toolkit can be used to generate all the necessary keys to enable HTTPS in apache NiFi.
