Hive安装过程，集成本地Mysql

话不多说，简单粗暴：

1. Hive下载地址及下载方式：

官方网址：https://hive.apache.org/downloads.html   
Linux下载方式：wget http://mirrors.tuna.tsinghua.edu.cn/apache/hadoop/common/hadoop-2.8.4/hadoop-2.8.4.tar.gz

存储路径、解压等不再详细赘述。

2. 下载MySql连接Jar包【Maven 仓库选择适当版本即可，本Demo使用 mysql-connector-java-5.1.45.jar】：

http://mvnrepository.com/artifact/mysql/mysql-connector-java

3. 增加Hive环境变量：

使用命令：vim /etc/profile

增加内容：

#HIVE
HIVE_HOME=/opt/apache-hive-2.3.3-bin
HIVE_CONF_DIR=$HIVE_HOME/conf
PATH=.:$PATH:$HADOOP_HOME/bin:$HIVE_HOME/bin

确认是否成功

hive –-version  //注意：这里是两个 -

配置成功如下图所示：

4. 配置集成Mysql数据库

4.1 到hive中的conf目录下，执行如下操作：

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

主要是配置Mysql的连接信息：

//增加如下代码【注意，一定要删除或注释文件中相同的配置。注意，注意，注意。否则会报错】
    <property>
        <name>javax.jdo.option.ConnectionUserName</name>　　//删除文件中原有property
        <value>hadoop</value>
    </property>
    <property>
        <name>javax.jdo.option.ConnectionPassword</name>　　//删除文件中原有property
        <value>hadoop</value>
    </property>
   <property>
        <name>javax.jdo.option.ConnectionURL</name>　　　　//删除文件中原有property
        <value>jdbc:mysql://localhost:3306/aaaTest?createDatabaseIfNoExist=true</value>
        <!-- <value>jdbc:mysql://*.*.*.*:3306/aaaTest?createDatabaseIfNoExist=true</value> -->
    </property>
 </property>
    <property>
        <name>javax.jdo.option.ConnectionDriverName</name>　　//删除文件中原有property
        <value>com.mysql.jdbc.Driver</value>
    </property>
//增加结束

//修改以下属性为  true
<property>
    <name>hive.metastore.local</name>　　//修改文件中原有property
    <value>true</value>
  </property>

4.2 再次执行 hive 命令：

show databases;

至此，Hive安装成功。

以上仅供参考，如果有问题可留意及时沟通。
