TiSpark 部署拓扑
本文介绍 TiSpark 部署的拓扑,以及如何在最小拓扑的基础上同时部署 TiSpark。TiSpark 是平凯星辰为解决用户复杂 OLAP 需求而推出的产品。它借助 Spark 平台,同时融合 TiKV 分布式集群的优势,和平凯数据库一起为用户一站式解决 HTAP (Hybrid Transactional/Analytical Processing) 的需求。
关于 TiSpark 的架构介绍与使用,参见 TiSpark 用户指南。
警告:
TiUP Cluster 的 TiSpark 支持目前为废弃状态,不建议使用。

拓扑模版
注意
user: "tidb":表示通过tidb系统用户来做集群的内部管理,默认使用 22 端口通过 ssh 登录目标机器。- 下列(简单、详细)模版中的平凯数据库拓扑实例的 IP 为示例 IP。在实际部署时,请替换为实际的 IP。

注意
- 无需手动创建配置文件中的
tidb用户,TiUP cluster 组件会在目标主机上自动创建该用户。可以自定义用户,也可以和中控机的用户保持一致。- 如果部署目录配置为相对路径,会部署在用户的 Home 目录下。
环境要求
由于 TiSpark 基于 Apache Spark 集群,在启动包含 TiSpark 组件的 TiDB 集群前,需要在部署了 TiSpark 组件的服务器上安装 Java 运行时环境(JRE) 8,否则将无法启动相关组件。
TiUP 不提供自动安装 JRE 的支持,该操作需要用户自行完成。JRE 8 的安装方法可以参考 OpenJDK 的文档说明。
如果部署服务器上已经安装有 JRE 8,但不在系统的默认包管理工具路径中,可以通过在拓扑配置中设置 java_home 参数来指定要使用的 JRE 环境所在的路径。该参数对应系统环境变量 JAVA_HOME。
