mysql做hive元數據庫

vim conf/hive-site.xml

<property>  

  <name>javax.jdo.option.ConnectionURL</name>  

  <value>jdbc:mysql://192.168.4.150:3306/hive?createDatabaseIfNotExist=true</value>  

  <description>JDBC connect string for a JDBC metastore</description>  

</property>  

<property>  

  <name>javax.jdo.option.ConnectionDriverName</name>  

  <value>com.mysql.jdbc.Driver</value>  

  <description>Driver class name for a JDBC metastore</description>  

</property>  

  

<property>  

  <name>javax.jdo.option.ConnectionUserName</name>  

  <value>hive</value>  

  <description>username to use against metastore database</description>  

</property>  

  

<property>  

  <name>javax.jdo.option.ConnectionPassword</name>  

  <value>hive</value>  

  <description>password to use against metastore database</description>  

</property>  

mysql鏈接配置

建立hive用戶密碼hive，並賦予權限

mysql> CREATE USER 'hive' IDENTIFIED BY 'hive';

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

mysql> flush privileges;

vim /etc/mysql/my.cnf

 

將"# bind-address           = 127.0.0.1 「 有就註釋掉。

重啓mysql服務： service mysql restart

添加jdbc包到hive/lib下面   mysql-connector-java-5.1.6-bin.jar

此時再啓動hive就能夠啦

以前的數據也看不到了 ，想要以前的文件，去掉配置重啓就行
