hive的安装

在安装hdoop以后，打算安装hive,数据库用mysql。在安装的过程中还是经过了一番周折的。记录下来，希望对大家有帮助。
1. Hadoop的安装
请参考http://blog.csdn.net/ydd326/article/details/6860304
2. MySQL的安装
sudo apt-get install mysql-server
根用户进入
#mysql -u root
创建数据库hive
mysql> create database hive;
设置用户和密码
mysql> create user 'hive'@'localhost' identified by 'admin';
设置权限
grant all privileges on hive.* to 'hive'@'localhost' with grant option;
重启MySQL

3. Hive的安装
下载hive-0.7.0-bin.tar.gz包
解压
tar xzvf hive-0.7.0-vin.tar.gz
进入目录
cd hive-0.7.0-bin
修改hive-0.7.0-bin/bin/hive-config.sh,添加
export HADOOP_HOME= your hadoop home path

修改conf/hive-site.xml

<?xml version="1.0"?> 
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?> 

<!-- Put site-specific property overrides in this file. --> 

<configuration> 

<property> 
  <name>hive.metastore.local</name> 
  <value>true</value> 
</property> 

<property> 
        <name>javax.jdo.option.ConnectionURL</name> 
        <value>jdbc:mysql://localhost:3306/hive?createDatabaseIfNotExist=true</value> 
        <description>JDBC connect string FOR a JDBC metastore</description> 
</property> 

<property> 
        <name>javax.jdo.option.ConnectionDriverName</name> 
        <value>com.mysql.jdbc.Driver</value> 
        <description>Driver class name FOR a JDBC metastore</description> 
</property> 

<property> 
        <name>javax.jdo.option.ConnectionUserName</name> 
        <value>hive</value> 
        <description>username TOUSE against metastore database</description> 
</property> 
<property> 
        <name>javax.jdo.option.ConnectionPassword</name> 
        <value>admin</value> 
        <description>password TOUSE against metastore database</description> 
</property> 

</configuration>

设置 ~/.bashrc

添加

export HADOOP_HOME=/usr/hadoop/hadoop
	export HADOOP_CONF_DIR=$HOME/config
	export HIVE_HOME=/usr/hadoop/hadoop/hive-0.7.0-bin
	export HIVE_CONF_DIR=$HOME/hive-config
	export PATH=$PATH:$HADOOP_HOME/bin:$HIVE_HOME/bin

启动hive (启动hive前清先启动hadoop,mysql)
./bin/hive
hive>show tables;
OK.
