安装hive3.1.2

一、安装

#下载
$ wget https://mirrors.tuna.tsinghua.edu.cn/apache/hive/hive-3.1.2/apache-hive-3.1.2-bin.tar.gz

#解压，路径为/Users/zheng/hive-3.1.2/conf
$ tar -zxvf apache-hive-3.1.2-bin.tar.gz
$ mv apache-hive-3.1.2-bin/ hive-3.1.2


#下载mysql-connector-java-5.1.48.jar
wget https://repo1.maven.org/maven2/mysql/mysql-connector-java/5.1.48/mysql-connector-java-5.1.48.jar

#复制到hive lib目录下
cp mysql-connector-java-5.1.48.jar /Users/zheng/hive-3.1.2/lib

#设置环境变量
vim /etc/profile

#新增
export HIVE_HOME=/Users/zheng/hive-3.1.2
export PATH=$PATH:$HIVE_HOME/bin

#检查环境变量是否配置成功
hive version

执行hive version报错：

SLF4J: Class path contains multiple SLF4J bindings.

原因：本地安装了hadoop，/hadoop-3.2.1/share/hadoop/common/lib目录下有个guava-27.0-jre.jar和/hive-3.1.2/lib下的guava-19.0.jar版本不一致，删除低版本guava-19.0.jar，拷贝/hadoop-3.2.1/share/hadoop/common/lib/guava-27.0-jre.jar到/hive-3.1.2/lib目录下。注意：必须使用高版本，使用低版本还是会报错

 

二、修改配置 

cd /Users/zheng/hive-3.1.2/conf

cp hive-env.sh.template  hive-env.sh

cp hive-default.xml.template hive-site.xml

#修改hive-site.xml文件内以下参数,configuration内的参数全部删除，只留下以下参数并根据本地mysql数据库设置相应用户名密码
vim hive-site.xml


 
      javax.jdo.option.ConnectionDriverName
      com.mysql.jdbc.Driver
  
  
      javax.jdo.option.ConnectionURL
      jdbc:mysql://localhost:3306/hive?createDatabaseIfNotExist=true&characterEncoding=utf8&useSSL=true
  
  
      javax.jdo.option.ConnectionUserName
      root
   
  
      javax.jdo.option.ConnectionPassword
      yourpassword
  
  
      hive.metastore.warehouse.dir
      /Users/zheng/hive/warehouse
  

三、初始化metastore

#初始化metastore
$ cd /Users/zheng/hive/hive-3.1.2/bin
$ schematool -dbType mysql -initSchema

执行schematool -dbType mysql -initSchema报命令找不到，回看了下发现是hive-site.xml里的密码写错了,执行成功后会看到以下数据库

确认初始化成功

#进入hive
$ hive


#查看数据库
hive> show databases;
OK
default
Time taken: 1.011 seconds, Fetched: 1 row(s)
hive>

网上看到有些在hive-env.sh设置了环境变量之类的，这里由于已经在本地的/etc/profile通过全局的方式设置过了，故不需要再设置。
