進入mysql

mysql -uroot -p //預設沒有密碼

為hive建立相應的使用者以及密碼

 CREATE USER 'hive' IDENTIFIED BY 'mysql';

授權hive使用者訪問許可權

 GRANT ALL PRIVILEGES ON *.* TO 'hive'@'%' WITH GRANT OPTION;

建立hive資料庫

mysql -uhive -pmysql//以hive使用者進入mysql
create database hive;

將mysql的jdbc驅動放置到hive的lib目錄下

wget http://dev.mysql
 
.com/get/Downloads/Connector-J/mysql-connector-java-5.1.11.tar.gz/from/http://mysql.he.net/
tar -xvzf mysql-connector-java-5.1.11.tar.gz
cp mysql-connector-java-5.1.11/*.jar $HIVE_HOME/lib

接下來配置hive.site.xml

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>

<configuration
 
>
    <property>
        <name>hive.metastore.local</name>
        <value>true</value>
    </property>
    <property>
        <name>javax.jdo.option.ConnectionURL</name>
        <value>jdbc:mysql://localhost:3306/hive?characterEncoding=UTF-8</value
 
>
    </property>
    <property>
        <name>javax.jdo.option.ConnectionDriverName</name>
        <value>com.mysql.jdbc.Driver</value>
    </property>
    <property>
        <name>javax.jdo.option.ConnectionUserName</name>
        <value>hive</value>
    </property>
    <property>
        <name>javax.jdo.option.ConnectionPassword</name>
        <value>mysql</value>
    </property>
</configuration>

修改為mysql

schematool -initSchema -dbType mysql

遇到的問題：

Warning: Using a password on the command line interface can be insecure.
ERROR 1045 (28000): Access denied for user 'hive'@'localhost' (using password: YES)

這是由於我們設定的時候允許全網段的訪問，忽略了localhost

可以這樣改（為其新增一個localhost）：

grant all privileges on *.* to [email protected] identified by 'pass' with grant option;
