Description:
zh-cn: 在现有VPC基础上，自动化部署Hive集群，含管理节点EIP，弹性伸缩的Worker节点，预装JDK1.8、Hadoop2.7.7、Scala2.12.1、Spark2.1.0、Hive2.3.7。安全组配置支持Spark8080和Hive10001端口访问。
en: Automate the deployment of a Hive cluster on top of the existing Virtual Private
Cloud (VPC), encompassing a management node equipped with an Elastic IP (EIP),
and worker nodes designed for elasticity and scaling. The nodes come pre-installed
with Java Development Kit (JDK) version 1.8, Hadoop 2.7.7, Scala 2.12.1, Spark
2.1.0, and Hive 2.3.7. The security group configurations are tailored to facilitate
access through ports 8080 for Spark and 10001 for Hive, ensuring secure connectivity.
