Hive的安装和配置

Posted 2020-10-05 kwz

前提是：hadoop必须已经启动了***

        1°、解压hive的安装包
            [[email protected] soft]# tar -zxvf apache-hive-0.14.0-bin.tar.gz -C ../
        2°、备份配置文件
            [[email protected] conf]# cp hive-env.sh.template hive-env.sh
            [[email protected] conf]# cp hive-default.xml.template hive-site.xml
        3°、配置hive的配置文件

1）、修改hive-env.sh
                加入三行内容（大家根据自己的情况来添加）
                    JAVA_HOME=/usr/local/jdk1.7.0_55
                    HADOOP_HOME=/usr/local/hadoop-2.4.1
                    HIVE_HOME=/usr/local/hive-0.14.0

2）、修改hive-site.xml

<configuration>
<property>
  <name>javax.jdo.option.ConnectionURL</name>
 <value>jdbc:mysql://192.168.1.121:3306/hive?characterEncoding=utf-8</value>
 <description>JDBC connect string for aJDBCmetastore</description>
</property>
<property>
 <name>javax.jdo.option.ConnectionDriverName</name>
 <value>com.mysql.jdbc.Driver</value>
 <description>Driver class name for aJDBCmetastore</description>
</property>
<property>
 <name>javax.jdo.option.ConnectionUserName</name>
 <value>hive</value>
 <description>username to use againstmetastoredatabase</description>
</property>
<property>
 <name>javax.jdo.option.ConnectionPassword</name>
 <value>hive</value>
 <description>password to use againstmetastoredatabase</description>
</property>
<property>
 <name>hive.metastore.schema.verification</name>
 <value>false</value>
</property>
</configuration>

3）、拷贝mysql驱动到$HIVE_HOME/lib目录下
            [[email protected] bin]# cp /usr/local/soft/mysql-connector-java-5.1.17.jar ../lib/

4）、启动Hive

[[email protected] bin]# ./hive <==>等价于
[[email protected] bin]# ./hive --service cli
