hive 三种搭建方式

1本地模式

<?xml version="1.0" encoding="UTF-8" standalone="no"?>

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

<configuration> 

    <property>  

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

          <value>jdbc:derby:;databaseName=metastore_db;create=true</value>  

    </property>  

    <property>  

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

          <value>org.apache.derby.jdbc.EmbeddedDriver</value>  

    </property>  

    <property>  

          <name>hive.metastore.local</name>  

          <value>true</value>  

    </property> 

    <property>  

          <name>hive.metastore.warehouse.dir</name>  

          <value>/user/hive/warehouse</value>  

    </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，否则会提示错误

2单用户模式（mysql）

<?xml version="1.0" encoding="UTF-8" standalone="no"?>

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

<configuration>  

    <property>  

          <name>hive.metastore.warehouse.dir</name>  

          <value>/user/hive_remote/warehouse</value>  

    </property> 

    <property>  

          <name>hive.metastore.local</name>  

          <value>true</value>  

    </property> 

    <property>  

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

          <value>jdbc:mysql://localhost/hive_remote?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>hive</value>  

    </property> 

    <property>  

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

          <value>password</value>  

    </property>  

</configuration>  

3 多用户模式

将hive-site.xml配置文件拆为如下两部分

         1）、服务端配置文件

<?xml version="1.0" encoding="UTF-8" standalone="no"?>

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

<configuration>

        <property>

        <name>hive.metastore.warehouse.dir</name>    

        <value>/user/hive/warehouse</value>

    </property>

    <property>

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

        <value>jdbc:mysql://192.168.189.33:3306/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>123</value>

    </property>

</configuration>

         2）、客户端配置文件

<?xml version="1.0" encoding="UTF-8" standalone="no"?>

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

<configuration>

    <property>  

          <name>hive.metastore.warehouse.dir</name>     与服务器端对应

          <value>/user/hive/warehouse</value>  

    </property>   

    <property>  

          <name>hive.metastore.local</name>  

          <value>false</value>  

      </property> 

      <property>  

          <name>hive.metastore.uris</name>  

          <value>thrift://metastoreserver的ip:9083</value>  

    </property> 

</configuration>

启动hive服务端程序

 hive --service metastore  

客户端直接使用hive命令即可

注意事项：

一  2,3方法

mysql的jar包拷贝到$HIVE_HOME/lib目录下

mysql-connector-java-5.1.32-bin.jar

二

[ERROR] Terminal initialization failed; falling back to unsupported

java.lang.IncompatibleClassChangeError: Found class jline.Terminal, but interface was expected

at jline.TerminalFactory.create(TerminalFactory.java:101)

错误的原因： Hadoop jline版本和hive的jline不一致，hive的jline版本新一点

把hive的jline包拷到/hadoop-2.6.5/share/hadoop/yarn下

多用户模式下

服务器端需要

mysql-connector-java-5.1.32-bin.jar

不需要jline包

客户端只需要换yarn的jline包
