Hive的安装部署

1.环境准备

1.1软件版本

hive-0.14 下载地址

2.配置

安装hive的前提，必需安装好hadoop环境，可以参考我之前Hadoop社区版搭建，先搭建好hadoop环境；接下来我们开始配置hive

2.1环境变量

sudo vi /etc/profile

HIVE_HOME=/home/hadoop/source/hive-0.14.0
PATH=$HIVE_HOME/bin
export  HIVE_HOME 

2.2hive-site.xml

<configuration>
<property>   
  <name>datanucleus.fixedDatastore</name>   
  <value>false</value>   
</property>
<property>
  <name>hive.metastore.execute.setugi</name>
  <value>true</value>
</property>

<property>
  <name>hive.metastore.warehouse.dir</name>
  <value>/home/hive/warehouse</value>
  <description>location of default database for the warehouse</description>
</property>

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

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

</property>

<property>
  <name>javax.jdo.option.ConnectionUserName</name>
  <value>root</value>
  <description>username to use against metastore database</description>
</property>

<property>
  <name>javax.jdo.option.ConnectionPassword</name>
  <value>root</value>
  <description>password to use against metastore database</description>
</property>

<property>
  <name>hive.hwi.listen.host</name>
  <value>10.211.55.18</value>
  <description>This is the host address the Hive Web Interface will listen on</description>
</property>

<property>
  <name>hive.hwi.listen.port</name>
  <value>9999</value>
  <description>This is the port the Hive Web Interface will listen on</description>
</property>

<!-- configure hwi war package location -->
<!--
<property>
  <name>hive.hwi.war.file</name>
  <value>lib/hive-hwi-0.14.0.war</value>
  <description>This is the WAR file with the jsp content for Hive Web Interface</description>
</property>
-->
</configuration>

 2.3hive-env.sh

# Set HADOOP_HOME to point to a specific hadoop install directory
HADOOP_HOME=/home/hadoop/source/hadoop-2.5.1

2.4启动

[[email protected] ~]$ hive

Logging initialized using configuration in file:/home/hadoop/source/hive-0.14.0/conf/hive-log4j.properties
SLF4J: Class path contains multiple SLF4J bindings.

hive>

至此，hive配置完成。

注：由于配置的是mysql驱动，所以需要把mysql的驱动包放到$HIVE_HOME/lib下
