基于Hadoop2.6.5(HA)的Hive1.2.1的MySQL方式配置

1.Hive配置MySQL

Hive只是一个工具，无需配置多台机器，我在CentOS7One机器上配置Hive

/usr/local/hive/apache-hive-1.2.1-bin/conf

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

编辑hive-site.xml

配置MySQL连接地址

  <property>
    <name>javax.jdo.option.ConnectionURL</name>
    <value>jdbc:mysql://192.168.1.161:3306/hive?createDatabaseIfNotExist=true</value>
    <description>JDBC connect string for a JDBC metastore</description>
  </property>

配置MySQL驱动包

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

配置数据库用户名

  <property>
    <name>javax.jdo.option.ConnectionUserName</name>
    <value>root</value>
    <description>Username to use against metastore database</description>
  </property>

配置数据库密码

  <property>
    <name>javax.jdo.option.ConnectionPassword</name>
    <value></value>
    <description>password to use against metastore database</description>
  </property>

在CentOS7One上启动hive

sh /usr/local/hive/apache-hive-1.2.-bin/bin/hive

2.注意事项

MySQL驱动包要加入到hive的lib目录下(/usr/local/hive/apache-hive-1.2.1-bin/lib),mysql-connector-java-5.1.28.jar
