hive的mysql配置笔记

配置hive使用mysql数据库

------------------------

1.下载并加压hive.tar.gz

2.配置环境变量

HIVE_HOME=...

PATH=..:$HIVE_HOME/bin:$HIVE_HOME/conf

$>source /etc/environment

3.创建配置文件

$>cd conf

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

$ cp hive-env.sh.template hive-env.sh

$ cp hive-exec-log4j.properties.template hive-execlog4j.properties

$ cp hive-log4j.properties.template hive-log4j.properties

4.修改conf/hive-env.sh配置文件

export HADOOP_HOME=/soft/hadoop

export HIVE_CONF_DIR=/soft/hive/conf

5.修改conf/hive-site.xml文件

hive.metastore.warehourse.dir=/user/hive/warehouse //hdfs系统

hive.exec.scratchdir=/tmp/hive-${user.name} //hdfs系统

6.配置使用mysql数据库

0.在mysql上创建myhive数据库

create database myhive ;

1.配置hive-ste.xml

[conf/hive-site.xml]

#javax.jdo.option.ConnectionURL // the database URL

#javax.jdo.option.ConnectionDriverName // the JDBC driver name

#javax.jdo.option.ConnectionUserName // database username
