1、软件环境

RHEL6 角色 jdk
hadoop-2.8.1.tar.gz    
apache-maven-3.3.9   mysql-5.1
xx.xx.xx.xx ip地址 NN hadoop01
xx.xx.xx.xx ip地址 DN hadoop02
xx.xx.xx.xx ip地址 DN hadoop03
xx.xx.xx.xx ip地址 DN hadoop04
xx.xx.xx.xx ip地址 DN hadoop05

本次涉及伪分布式部署只是要主机hadoop01，软件安装参考伪分布式部署终极篇

编译hive之前，我们需要阅读编译hive的readme.txt 以便我们下在相应的软件版本

Requirements

============

- Java 1.6, 1.7  ---jdk只能使用1.6或者1.7 不能使用1.8

- Hadoop 1.x, 2.x

2、安装jdk

mkdir  /usr/java && cd  /usr/java/   
tar -zxvf  /tmp/server-jre-7u80-linux-x64.tar.gz
chown -R root:root  /usr/java/jdk1.7.0_80/
echo 'export JAVA_HOME=/usr/java/jdk1.7.0_80'>>/etc/profile
source /etc/profile

3、安装maven

cd /usr/local/
unzip /tmp/apache-maven-3.3.9-bin.zip
chown root: /usr/local/apache-maven-3.3.9 -R
echo 'export MAVEN_HOME=/usr/local/apache-maven-3.3.9'>>/etc/profile
echo 'export MAVEN_OPTS="-Xms256m -Xmx512m"'>>/etc/profile
echo 'export PATH=$MAVEN_HOME/bin:$JAVA_HOME/bin:$PATH'>>/etc/profile
source /etc/profile

--JDK 和maven部署可参考---

4、安装mysql

yum -y install mysql-server mysql
/etc/init.d/mysqld start
chkconfig mysqld on
mysqladmin -u root password 123456
mysql -uroot -p123456
use mysql;
GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' IDENTIFIED BY 'v123456' WITH GRANT OPTION;
GRANT ALL PRIVILEGES ON *.* TO 'root'@'127.0.0.1' IDENTIFIED BY '123456' WITH GRANT OPTION;
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;
update user set password=password('123456') where user='root';
delete from user where not (user='root') ;
delete from user where user='root' and password='';
drop database test;
DROP USER ''@'%';
flush privileges;

5、下载hive源码包：

#
# 根据cdh版本选择对应hive软件包：
# hive-1.1.0-cdh5.7.1-src.tar.gz
# 解压后使用maven命令编译成安装包

6、编译:

cd /tmp/
tar -xf hive-1.1.0-cdh5.7.1-src.tar.gz
cd /tmp/hive-1.1.0-cdh5.7.1
mvn clean package -DskipTests -Phadoop-2 -Pdist
# 编译生成的包在以下位置：
# packaging/target/apache-hive-1.1.0-cdh5.7.1-bin.tar.gz

7、安装编译生成的Hive包，然后测试

cd /usr/local/
tar -xf /tmp/apache-hive-1.1.0-cdh5.7.1-bin.tar.gz
ln -s apache-hive-1.1.0-cdh5.7.1-bin hive
chown -R hadoop:hadoop apache-hive-1.1.0-cdh5.7.1-bin
chown -R hadoop:hadoop hive
echo 'export HIVE_HOME=/usr/local/hive'>>/etc/profile
echo 'export PATH=$HIVE_HOME/bin:$PATH'>>/etc/profile

8、更改环境变量

su - hadoop
cd /usr/local/hive
cd conf

1、hive-env.sh

cp hive-env.sh.template  hive-env.sh&&vi hive-env.sh
HADOOP_HOME=/usr/local/hadoop

2、hive-site.xml

vi hive-site.xml

<?xml version="1.0"?>

<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
    <property>
        <name>javax.jdo.option.ConnectionURL</name>
        <value>jdbc:mysql://localhost:3306/vincent_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>vincent</value>
    </property>
</configuration>

 

9、拷贝mysql驱动包到$HIVE_HOME/lib

# 上方的hive-site.xml使用了java的mysql驱动包
# 需要将这个包上传到hive的lib目录之下
# 解压 mysql-connector-java-5.1.45.zip 对应的文件到目录即可
cd /tmp
unzip mysql-connector-java-5.1.45.zip
cd mysql-connector-java-5.1.45
cp mysql-connector-java-5.1.45-bin.jar /usr/local/hive/lib/

未拷贝有相关报错：

The specified datastore driver ("com.mysql.jdbc.Driver") was not found in the CLASSPATH.
Please check your CLASSPATH specification,
and the name of the driver.
