Hive的安装

Hive的安装

 

第一步：解压并安装：第二步：配置

1）root用户下，解压后，改名为hive，并将hive文件夹赋给hadoop用户

　　tar -zxvf hive-0.9.0.tar.gz -C /opt

　　mv hive-0.9.0.tar.gz hive

　　chown -R hadoop:hadoop hive

 

第二步：配置

在hadoop用户下

1）配置vi hive-env.sh：

hive/conf文件夹下提供了一个模板文件hive-env.sh.template，复制一份并改名为hive-env.sh

　　cp hive-env.sh.template hive-env.sh

　　vi hive-env.sh

      添加下面内容

　　　　export JAVA_HOME=/usr/program/jdk1.6.0_13/

　　　　export HIVE_HOME=/opt/hive

　　　　export PATH=$PATH:$HIVE_HOME/bin

　　　　export HADOOP_HOME=/home/hadoop/hadoop-env/hadoop-1.0.1

 

 

2）配置hive-site.xml

    a）vi hive-default.xml.template

        复制该文件前面的部分，如下：

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