?安装MySQL服务端
[[email protected] local]# rpm -i MySQL-server-5.5.31-2.el6.i686.rpmPLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !To do so, start the server, then issue the following commands:/usr/bin/mysqladmin -u root password 'new-password'/usr/bin/mysqladmin -u root -h centos password 'new-password'Alternatively you can run:/usr/bin/mysql_secure_installationwhich will also give you the option of removing the testdatabases and anonymous user created by default. This isstrongly recommended for production servers.See the manual for more instructions.Please report any problems with the /usr/bin/mysqlbug script!

把mysql的jdbc驱动放置到hive的lib目录下
[[email protected] local]# cp mysql-connector-java-5.1.10.jar /usr/local/hive-0.9.0/lib/
?修改hive-site.xml文件
<property> <name>javax.jdo.option.ConnectionURL</name> <value>jdbc:mysql://centos:3306/hive?createDatabaseIfNotExist=true</value> </property> <property> <name>javax.jdo.option.ConnectionDriverName</name> <value>com.mysql.jdbc.Driver</value> </property> <property> <name>javax.jdo.option.ConnectionUserName</name> <value>root</value> </property> <property> <name>javax.jdo.option.ConnectionPassword</name> <value>root</value> </property>
?让MySQL的root用户允许远程连接访问
mysql> grant all on hive.* to 'root'@'%' identified by 'root';Query OK, 0 rows affected (0.15 sec)mysql> flush privileges;Query OK, 0 rows affected (0.00 sec)
?在MySQL查看hive所创建的表
mysql> show databases;+--------------------+| Database |+--------------------+| information_schema || hive || mysql || performance_schema || test |+--------------------+5 rows in set (0.02 sec)mysql> use hiveReading table information for completion of table and column namesYou can turn off this feature to get a quicker startup with -ADatabase changedmysql> show tables;+-----------------+| Tables_in_hive |+-----------------+| BUCKETING_COLS || CDS || COLUMNS_V2 || DATABASE_PARAMS || DBS || PARTITION_KEYS || SDS || SD_PARAMS || SEQUENCE_TABLE || SERDES || SERDE_PARAMS || SORT_COLS || TABLE_PARAMS || TBLS |+-----------------+14 rows in set (0.00 sec)
