Big data-the most detailed compilation and deployment of tar in Hive
1. Software Environment RHEL6 Role jdkhadoop-2.8.1.tar.gzapache-maven-3.3.9mysql-5.1xx.xx.xx ip address NNhadoop01xx.xx.xx ip address DNhadoop02xx.xx.xx ip address DNhadoop03xx.xx.xx ip address DNhadoop04xx.xx ip address DNhadoop05
This involves pseudo-distributed deployment only to host hadoop01, software installation reference pseudo-distributed deployment final chapter
Before compiling hive, we need to read readme.txt of compiled hive so that we can download the corresponding software version
Requirements
============
- Java 1.6, 1.7 ---jdk can only use 1.6 or 1.7, not 1.8
- Hadoop 1.x, 2.x
2. Install 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. Install 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

4. Install 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. Download hive source package:
# http://archive.cloudera.com/cdh6/cdh/5/
#Select Hive package according to CDH version:
# hive-1.1.0-cdh6.7.1-src.tar.gz
#After decompression, use maven command to compile into installation package
6. Compile:
cd /tmp/
tar -xf hive-1.1.0-cdh6.7.1-src.tar.gz
cd /tmp/hive-1.1.0-cdh6.7.1
mvn clean package -DskipTests -Phadoop-2 -Pdist
#Compile generated packages in the following locations:
# packaging/target/apache-hive-1.1.0-cdh6.7.1-bin.tar.gz
7. Install the compiled Hive package and test it.
cd /usr/local/
tar -xf /tmp/apache-hive-1.1.0-cdh6.7.1-bin.tar.gz
ln -s apache-hive-1.1.0-cdh6.7.1-bin hive
chown -R hadoop:hadoop apache-hive-1.1.0-cdh6.7.1-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. Change environment variables
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
javax.jdo.option.ConnectionURL
jdbc:mysql://localhost:3306/vincent_hive? createDatabaseIfNotExist=true
javax.jdo.option.ConnectionDriverName
com.mysql.jdbc.Driver
javax.jdo.option.ConnectionUserName
root
javax.jdo.option.ConnectionPassword
vincent
9, Copy mysql driver package to $HIVE_HOME/lib
#hive-site.xml above uses java mysql driver package
#Need to upload this package to hive under lib directory
#Unzip the file corresponding to mysql-connector-java-5.1.45.zip to the directory
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/
