搭建Hadoop2.7.3+Hive2.1.1及 mysql(配置Hive+Hadoop）(二)

例子：下载mysql-connector-java-5.1.41.tar

1、解压连接器connector文件

1.1、解压

[root@localhost Software]# tar xzfmysql-connector-java-5.1.41.tar.gz
[root@localhost Software]# cd mysql-connector-java-5.1.41/

1.2、查看文件夹

[root@localhostmysql-connector-java-5.1.41]# ll

1.3、Copy到hive/lib路径下

[root@localhost Software]# cpmysql-connector-java-5.1.41/mysql-connector-java-5.1.41-bin.jar/usr/hive/lib/mysql-connector-java-5.1.41-bin.jar

2、登陆MySQL创建数据库:hive_db（注意配置hive-site.xml时有指定）

2.1、用户名:root 密码:password，另开一个终端登陆MySQL,创建数据库hive_db

[root@localhost hive]# mysql -u root -ppassword

mysql> create database hive_db;

3、改配置文件hive-site.xml

以下只列出改动的配置项，其它保留默认
