1.安装准备

Hadoop版本:2.7.2
mysql版本:5.7.3

下载安装包:
apache-hive-2.1.0-bin.tar.gz

解压重命名:

tar zxvf apache-hive-2.1.0-bin.tar.gz
mv apache-hive-2.1.0-bin hive

注意:
hive最好和hadoop在同一个用户下安装.

2.修改配置文件

• .bashrc

export HIVE_HOME=/home/wangkai/hive 
export PATH=$HIVE_HOME/bin:$HIVE_HOME/conf:$PATH

执行source ~/.bashrc

---

• hive-site.xml

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

修改内容如下:

<property>
  <name>system:java.io.tmpdir</name>
  <value>/home/wangkai/hive/iotmp</value>
</property>
<property>
  <name>javax.jdo.option.ConnectionURL</name>
  <value>jdbc:mysql://192.168.163.101:3306/hive?createDatabaseIfNotExist=true</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>root</value>
</property>
 <property>    
   <name>hive.metastore.schema.verification</name>    
   <value>false</value>
 </property>   
 <property>
    <name>hive.exec.local.scratchdir</name>
    <value>${system:java.io.tmpdir}/${user.name}</value>
  </property>

注:system:java.io.tmpdir对应的目录需要手工创建

mkdir -p /home/wangkai/hive/iotmp
chmod 777 /home/wangkai/hive/iotmp

---

• hive-env.sh

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

内容修改如下:

export HADOOP_HOME=/home/wangkai/hadoop 
export HIVE_CONF_DIR=/home/wangkai/hive/conf  
export HIVE_AUX_JARS_PATH=/home/wangkai/hive/lib

---

3.创建HDFS目录,赋权

hadoop fs -mkdir -p /user/hive/warehouse
hadoop fs -mkdir -p /tmp/hive/  
hadoop fs -chmod 777 /user/hive/warehouse  
hadoop fs -chmod 777 /tmp/hive 

---

4.授权数据库访问

grant all privileges on *.* to ‘root‘@‘centos7-1‘ identified by ‘root‘;
flush privileges;

---

5.添加mysql驱动包

将mysql-connector-java-5.1.30.jar拷贝至hive/lib中.

---

6.初始化数据库

schematool -initSchema -dbType mysql

---

7.启动

执行hive

---

8.测试

#查看所有数据库
show databases;
#查看default下的表
show tables;
#退出客户端
exit;
