一.Hive的安装部署

系统

Centos　6.5

hadoop 2.5.0

zookeeper 3.4.5

Hive 0.9.0

下载 解压就不说了

①:createDatabaseIfNotExist=true 表示如果该mysql数据库中没有名为"hive"的数据库则创建;

进入 hive/conf 目录

cd ./hive-0.9.0/conf

配置hive-site.xml

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

修改hive-site.xml配置

<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>root</value>
  <description>username to use against metastore database</description>
</property>


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

配置完以后启动 Hive
