CentOS7下Hive的安装配置

0、安装前提

安装配置jdk与hadoop
安装配置好mysql

1、下载上传

下载hive，地址:http://mirror.bit.edu.cn/apache/hive/
上传到指定位置scp apache-hive-3.1.2-bin.tar.gz root@Carlota1:/usr/local/apps

2、解压安装

tar -zxvf apache-hive-3.1.2-bin.tar.gz
mv apache-hive-3.1.2-bin hive-3.1.2

3、修改环境变量/etc/profile:

vi /etc/profile

#hive
export HIVE_HOME=/usr/local/apps/hive-3.1.2
export PATH=$PATH:$HIVE_HOME/bin
export HIVE_CONF_DIR=/usr/local/apps/hive-3.1.2/conf

sources /etc/profile

4、查看版本，验证安装成功

hive --version

5、配置

cd /usr/local/apps/hive-3.1.2/conf
vim hive-site.xml 添加以下内容

<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration><property><name>javax.jdo.option.ConnectionURL</name><value>jdbc:mysql://Carlota1:3306/hive</value></property><property><name>javax.jdo.option.ConnectionDriverName</name><value>com.mysql.jdbc.Driver</value></property><property><name>javax.jdo.option.ConnectionUserName</name><value>root</value></property><property><name>javax.jdo.option.ConnectionPassword</name><value>123456!</value></property><property><name>hive.metastore.schema.verification</name><value>false</value></property>
</configuration>

6、驱动拷贝

在官网下载mysql-connector-java-5.1.49.jar
复制Mysql的程序驱动mysql-connector-java-5.1.49.jar到hive/lib下

7、创建Mysql下的hive数据库

create database hive;

mysql> create database hive;
Query OK, 1 row affected (0.01 sec)

在Mysql中hive的schema创建schematool -dbType mysql -initSchema

schemaTool completed

这里会出现guava jar包的版本问题，解决方法参考这里

8、测试

键入hive
create database hive_1;

hive> create database hive_test;
OK
Time taken: 0.156 seconds
hive> show databases;
OK
default
hive_test
Time taken: 0.064 seconds, Fetched: 2 row(s)

9、观察Mysql下hive数据库的变化：

mysql> use hive;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -ADatabase changed
mysql> select * from DBS;

|     2 | NULL                  | hdfs://Carlota1:9000/user/hive/warehouse/hive_test.db | hive_test | root       | USER       | hive      |
+-------+-----------------------+-------------------------------------------------------+-----------+------------+------------+-----------+
