Hive配置
(只需要主機上配置)
MySQL數據庫安裝
元數據遷移到mysql
主機上先安裝mysql，用於存放hadoop元數據
Mysql驅動
下載一個數據包mysql-connector-java-5.1.18-bin.jar，放到hive的lib目錄下，
創建mysql用戶並賦權
創建hive數據庫
mysql>create database hive;
mysql>show databases;
+--------------------+
|Database |

|information_schema |
|hive |
|mysql |
|test |

創建hadoop用戶並設置密碼
mysql>insert into mysql.user(Host,User,Password)values("hadoop1","hadoop",password("hadoop"));
mysql>flush privileges;
[hadoop@hadoop1 ~]$ mysql -u hadoop -phadoop-h hadoop1
Welcome to the MySQL monitor. Commands end with ; or \g.

對hadoop用戶賦權
mysql>grant all privileges on hive.* to hadoop@hadoop1identified by ‘hadoop’;
mysql>flush privileges;
hive配置
軟件包下載
從官網上下載hive軟件包，上傳到服務器後，使用以下命令進行解壓：
[hadoop@hadoop1 soft]$ tar -zxvfapache-hive-0.13.1-bin.tar.gz
爲了配置方便，可以對解壓後的目錄進行修改名稱：
[hadoop@hadoop1 ~]$ mvapache-hive-0.13.1-bin hive2/
配置系統用戶環境變量
[hadoop@hadoop1 ~]$ cat .bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
.~/.bashrc
fi
# User specific environment and startupprograms
PATH=$PATH:$HOME/bin
export PATH
export JAVA_HOME=/usr/lib/jvm/java-1.7.0/
export HADOOP_HOME=/home/hadoop/hadoop2
export HIVE_HOME=/home/hadoop/hive2
export HIVE_CONF=/home/hadoop/hive2/conf
exportHIVE_CLASSPATH=$HIVE_HOME/lib:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
exportPATH=$PATH:$JAVA_HOME/bin/:$HADOOP_HOME/bin:$HIVE_HOME/bin
修改hive數據庫連接
在hive的conf目錄下創建文件hive-site.xml配置文件（數據庫連接等信息自定義）：
配置hive-site.xml 文件
<?xml version="1.0"?>
<?xml-stylesheettype="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
<name>hive.metastore.warehouse.dir</name>
<value>/hive2/warehouse</value>
</property>
<property>
<name>hive.querylog.location</name>
<value>/home/hadoop/hive2/log</value>
</property>
<property>
<name>hive.metastore.local</name>
<value>true</value>
</property>
<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql://hadoop1:3306/hive</value>
</property>
<property>
<name>javax.jdo.option.ConnectionDriverName</name>
<value>com.mysql.jdbc.Driver</value>
</property>
<property>
<name>javax.jdo.option.ConnectionUserName</name>
<value>hadoop</value>
</property>
<property>
<name>javax.jdo.option.ConnectionPassword</name>
<value>hadoop</value>
</property>
</configuration>
配置hive-env.sh文件
exportHIVE_CONF_DIR=/home/hadoop/hive2/conf
# Folder containing extra ibraries requiredfor hive compilation/execution can be controlled by:
# export HIVE_AUX_JARS_PATH=
exportHIVE_AUX_JARS_PATH=/home/hadoop/hive2/lib
Hive啓動運行
Cd/app/hive
./hive
查看數據表：
Showtables;
Ok，配置完成！
