hadoop hive安装，并使用mysql数据库

1、下载hive-0.12.0并解压到soft下

2、配置hive环境变量：

kun@hadoop-master:~$ sudo gedit /etc/profile

export HIVE_HOME=/home/kun/soft/hive-0.12.0<pre name="code" class="java">export PATH=:$HIVE_HOME/bin

kun@hadoop-master:~$ source /etc/profile

3、配置hive：

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

<?xml version="1.0" encoding="UTF-8" standalone="no"?><?xml-stylesheet type="text/xsl" href="configuration.xsl"?><configuration><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.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.ConnectionUserName</name>  <value>root</value>  <description>username to use against metastore database</description></property><property>  <name>javax.jdo.option.ConnectionPassword</name>  <value>123</value>  <description>password to use against metastore database</description></property><property>  <name>hive.metastore.local</name>  <value>true</value>  <description>controls whether to connect to remove metastore server or open a new metastore server in Hive Client JVM</description></property></configuration>

4、下载mysql-connector-java-5.1.28.jar包，并放置在lib下

5、直接在命令行输入hive
