CHAPTER TWO EASE OF USE You only need to be familiar with Structured Query Language (SQL) and Java Database Connectivity (JDBC) to handle massive data. It helps you focus on the design and implementation components required for Kyuubi to startup. For quick start deployment, the only thing you need is JAVA_HOME being correctly set. The Kyuubi release package you downloaded or built contains the rest prerequisites be sure is that your java runtime environment is correct. Setup JAVA You can either set it system-widely, e.g. in the .bashrc file. java -version java version "1.8.0_251" Java(TM) SE Runtime Environment
