Hive 三种运行方式之 本地 derby

这种方式是最简单的存储方式，只需要在hive-site.xml做如下配置便可

 
   
<configuration>  

<property>  
  <name>javax.jdo.option.ConnectionURLname>  
  <value>jdbc:derby:;databaseName=metastore_db;create=truevalue>  
property>  

<property>  
  <name>javax.jdo.option.ConnectionDriverNamename>  
  <value>org.apache.derby.jdbc.EmbeddedDrivervalue>  
property>  

<property>  
  <name>hive.metastore.localname>  
  <value>truevalue>  
property>  

<property>  
  <name>hive.metastore.warehouse.dirname>  
  <value>/user/hive/warehousevalue>  
property>  

configuration>

注：使用derby存储方式时，运行hive会在当前目录生成一个derby文件和一个metastore_db目录。这种存储方式的弊端是在同一个目录下同时只能有一个hive客户端能使用数据库，否则会提示如下错误
