Hive 远程多用户模式搭建

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>  
<!--hive2中无需配置此项
<property>  
  <name>hive.metastore.local</name>  
  <value>false</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

[[email protected] lib] hive --service metastore   

发现阻塞在此

[[email protected] conf]$ hive --service metastore
Starting Hive Metastore Server

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

[[email protected] conf]$ hive

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.

至此多用户模式配置完成。
