来源：互联网发布：找兼职知乎编辑：程序博客网时间：2024/05/02 00:06

之前已经在CentOS 6.7上安装部署Hadoop 2.7.2（http://blog.csdn.net/noob_f/article/details/53366756），并正常启动Hadoop集群。

将MySQL的JDBC驱动文件mysql-connector-java-5.1.40-bin.jar（该文件可在安装MySQL的lib目录下找到，我是在mysql官网下载的）复制到Hive的依赖库中

[root@master ~]# wget http://dev.mysql.com/get/Downloads/Connector-J/mysql-connector-java-5.1.40.tar.gz[root@master ~]#  tar zxvf mysql-connector-java-5.1.40.tar.gz[root@master ~]# cp mysql-connector-java-5.1.40/mysql-connector-java-5.1.40-bin.jar /usr/local/apache-hive-1.2.1-bin/lib/

设置MySQL

[root@master ~]# /etc/init.d/mysqld start[root@master ~]# mysql -u root -pEnter password:Welcome to the MySQL monitor.  Commands end with ; or \g.Your MySQL connection id is 2Server version: 5.1.73 Source distributionmysql> create database hiveDB;

修改root密码

mysql> use mysql;mysql> update user set password=password('root') where user='root';

刷新系统权限表

mysql> FLUSH PRIVILEGES;mysql> quit;

重新登录mysql

[root@master ~]# mysql -u root –pmysql> grant all privileges on hiveDB.* to 'root'@'%' identified by 'root';mysql> flush privileges;mysql> quit;

配置Hive

[root@master ~]# vi /usr/local/apache-hive-1.2.1-bin/conf/hive-env.sh.template

修改

# HADOOP_HOME=${bin}/../../hadoop

为

HADOOP_HOME=/usr/local/hadoop-2.7.2

保存退出

[root@master ~]# mv /usr/local/apache-hive-1.2.1-bin/conf/hive-env.sh.template /usr/local/apache-hive-1.2.1-bin/conf/hive-env.sh[root@master ~]# /usr/local/hadoop-2.7.2/bin/hdfs dfs -ls /16/11/25 19:08:51 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicableFound 2 itemsdrwx------   - root supergroup          0 2016-11-25 16:36 /tmpdrwxr-xr-x   - root supergroup          0 2016-11-25 01:16 /user

创建数据仓库操作过程中临时数据在HDFS上的转存目录

[root@master ~]# /usr/local/hadoop-2.7.2/bin/hdfs dfs -mkdir /tmp/hive

创建数据仓库操作过程中数据文件在HDFS上的存储目录

[root@master ~]# /usr/local/hadoop-2.7.2/bin/hdfs dfs -mkdir /user/hive[root@master ~]# /usr/local/hadoop-2.7.2/bin/hdfs dfs -mkdir /user/hive/warehouse

文件hive-site.xml内保存Hive运行时所需要的相关配置信息

[root@master ~]# vi /usr/local/apache-hive-1.2.1-bin/conf/hive-site.xml

添加

保存退出

属性hive.exec.scratchdir：执行Hive操作访问HDFS时用于存储临时数据的目录，默认为/tmp/目录，通常设置为/tmp/hive/。
属性hive.metastore.warehouse.dir：执行Hive数据仓库操作的数据存储目录，设置为HDFS存储路径hdfs://master_hostname:port/hive/warehouse，这里设为hdfs://master:9000/hive/warehouse。
属性javax.jdo.option.ConnectionDriverName：设置Hive连接MySQL的驱动名称，属性值为com.mysql.jdbc.Driver。
属性javax.jdo.option.ConnectionUserName：Hive连接存储metastore内容的数据库的用户名。
属性javax.jdo.option.ConnectionPassword：Hive连接存储metastore内容的数据库的密码。
属性javax.jdo.option.Multithreaded：是否允许Hive与MySQL之间存在多条连接，设置为true，表示允许。
属性javax.jdo.option.ConnectionURL：设置Hive通过JDBC模式连接MySQL数据库存储metastore内容，属性值为jdbc:mysql://host/database_name?createDatabaseIfNotExist=true，这里设为jdbc:mysql://master:3306/hiveDB?createDatabaseIfNotExist=true。
