4、编辑Hive配置文件
a、编辑 hive-env.sh ，指定 HADOOP_HOME 、HIVE_CONF_DIR
[grid@hadoop1 conf]$ pwd
/home/grid/apache-hive-1.0.0-bin/conf
[grid@hadoop1 conf]$ cp hive-env.sh.template hive-env.sh
[grid@hadoop1 conf]$ vim hive-env.sh
# Set HADOOP_HOME to point to a specific hadoop install directory
HADOOP_HOME=/home/grid/hadoop-1.2.1
# Hive Configuration Directory can be controlled by:
export HIVE_CONF_DIR=/home/grid/apache-hive-1.0.0-bin/conf
b、编辑 hive-site.xml ，修改数据库连接属性（javax.jdo.option.ConnectionURL/ConnectionDriverName/ConnectionUserName/ConnectionPassword）
[grid@hadoop1 conf]$ cp hive-default.xml.template hive-site.xml
[grid@hadoop1 conf]$ vi hive-site.xml
