安装HIVE
下载地址：http://archive.cloudera.com/cdh/3/
以版本 hive-0.7.1 为例
解压到安装路径: tar -xvf hive-0.7.1.tar.gz
将/conf/hive-env.sh.template 配置环境模板 拷贝一份
cp hive-env.sh.template hive-env.sh
添加以下配置项
#Hadoop 安装路径
HADOOP_HOME=/usr/local/hadoop/hadoop-0.20.2
#hive安装路径
export HIVE_HOME=/usr/local/hadoop/hive-0.7.1-cdh3u6
export PATH=$PATH:$HIVE_HOME/bin
#配置Ant LIB 库(启动后台管理服务需要用到)
export ANT_LIB=$ANT_HOME/lib
安装MySQL（略）
安装方法网上很多，这里就不介绍了。
安装完成后，可以使用命令行链接Mysql
mysql -h localhost -u root -p
创建个hive账户
CREATE USER 'hive' IDENTIFIED BY ‘123456‘;
#添加权限
GRANT ALL PRIVILEGES ON *.* TO 'hive'@'%' WITH GRANT OPTION;
建立Hive专用的元数据库
create database hive
修改hive-site.xml
（如果没有该文件，复制hive-default.xml并改名为hive-site.xml）
javax.jdo.option.ConnectionURL
jdbc:mysql://localhost:3306/hive?createDatabaseIfNotExist=true
JDBC connect string for a JDBC metastore
javax.jdo.option.ConnectionDriverName
com.mysql.jdbc.Driver
Driver class name for a JDBC metastore
javax.jdo.option.ConnectionUserName
hive
username to use against metastore database
javax.jdo.option.ConnectionPassword
123456
password to use against metastore database
把MySQL的JDBC驱动包(mysql-connector-java-5.1.*-bin.jar)复制到Hive的lib目录下。
启动hive
[root@idc01-vm-test-124 bin]# ./hive
Hive history file=/tmp/root/hive_job_log_root_201404201145_884718504.txt
hive>
show tables;
OK
Time taken: 2.962 seconds
#创建元数据表
hive> create table lss(id int,name string,age int) ROW FORMAT DELIMITED FIELDS TERMINATED BY '\t';
OK
Time taken: 0.467 seconds
#查看创建的表
hive> show tables;
OK
lss
#SELECT
hive> select * from lss;
OK
#接下来我们进入MySQL中看下hive库的信息
mysql> use hive;
Database changed
mysql> show tables;
