1.  在master和worker1上实现远程多用户模式搭建，mysql安装配置及hadoop配置工作在本站其他博客可见。
2.  服务端：

<configuration>  
    <property>  
      <name>hive.metastore.warehouse.dir</name>  
      <value>/user/hive/warehouse</value>  
    </property>  
    
    <property>  
      <name>javax.jdo.option.ConnectionURL</name>  
      <value>jdbc:mysql://master: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>

3.在worker1上配置hive-site.xml  
客户端：

<property>  
      <name>hive.metastore.warehouse.dir</name>  
      <value>/user/hive/warehouse</value>  
    </property>  
    
    <property>  
      <name>hive.metastore.uris</name>  
      <value>thrift://master:9083</value>  
    </property>

4.拷贝JDBC包  
将JDBC的jar包放入$HIVE\_HOME/lib目录下

[hadoop@master tgz]$ cp mysql-connector-java-5.1.19-bin.jar /app/hive/apache-hive-2.1.1-bin/lib/

5.拷贝jline扩展包  
将HIVE\_HOME/lib目录下的jline-2.12.jar包  
拷贝到HADOOP\_HOME/share/hadoop/yarn/lib目录下,  
并删除HADOOP\_HOME/share/hadoop/yarn/lib目录下旧版本的jline包

[hadoop@master lib]$ cp jline-2.12.jar /app/hadoop/hadoop-2.7.3/share/hadoop/yarn/lib/

1.  启动服务端

[hadoop@master lib] hive --service metastore

发现阻塞在此

[hadoop@master conf]$ hive --service metastore
    Starting Hive Metastore Server
    SLF4J: Class path contains multiple SLF4J bindings.
    SLF4J: Found binding in [jar:file:/app/hive/apache-hive-2.1.1-bin/lib/log4j-slf4j-impl-2.4.1.jar!/org/slf4j/impl/StaticLoggerBinder.class]
    SLF4J: Found binding in [jar:file:/app/hadoop/hadoop-2.7.3/share/hadoop/common/lib/slf4j-log4j12-1.7.10.jar!/org/slf4j/impl/StaticLoggerBinder.class]
    SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
    SLF4J: Actual binding is of type [org.apache.logging.slf4j.Log4jLoggerFactory]

因为客户端正在监听它：9083端口  
ss -nal |grep 9083  
7.启动客户端

[hadoop@worker1 conf]$ hive
    SLF4J: Class path contains multiple SLF4J bindings.
    SLF4J: Found binding in [jar:file:/app/hive/apache-hive-2.1.1-bin/lib/log4j-slf4j-impl-2.4.1.jar!/org/slf4j/impl/StaticLoggerBinder.class]
    SLF4J: Found binding in [jar:file:/app/hadoop/hadoop-2.7.3/share/hadoop/common/lib/slf4j-log4j12-1.7.10.jar!/org/slf4j/impl/StaticLoggerBinder.class]
    SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
    SLF4J: Actual binding is of type [org.apache.logging.slf4j.Log4jLoggerFactory]
    
    Logging initialized using configuration in file:/app/hive/apache-hive-2.1.1-bin/conf/hive-log4j2.properties Async: true
    Hive-on-MR is deprecated in Hive 2 and may not be available in the future versions. Consider using a different execution engine (i.e. spark, tez) or using Hive 1.X releases.
    hive> show databases;
    OK
    dblab
    default
    Time taken: 1.61 seconds, Fetched: 2 row(s)

至此多用户模式配置完成。
