Hadoop集成Hive

一、环境与软件准备

说明：服务器已用主机名代替，可根据自己的需求，改为IP地址

环境

服务器	组件
master	NameNode、DataNode、Nodemanager、ResourceManager、Hive、Hive的metastore、Hive的hiveserver2、mysql
Secondary	SecondaryNameNode、DataNode、NodeManager
Datanode	DataNode、NodeManager、Hive的beeline访问方式

1、java版本1.8

二、启动hadoop集群

$HADOOP_HOME/bin/hdfs namenode -format
start-all.sh
$HADOOP_HOME/bin/yarn --daemon start proxyserver
$HADOOP_HOME/bin/mapred --daemon start historyserver
四、webapp访问
hdfs
http://Master:9870/
yarn_node
http://Master:8088/

三、Hive的安装

1、Mysql的安装

linux$:] touch /etc/yum.repos.d/mysql.repo
linux$:] cat >/etc/yum.repos.d/mysql.repo  <<EOF
[mysql57-community]
name=MySQL 5.7 Community Server
baseurl=https://mirrors.cloud.tencent.com/mysql/yum/mysql-5.7-community-el7-x86_64/
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql
EOF
linux$:] yum clean all
linux$:] yum makecache
linux$:] yum -y install mysql-community-server
linux$:] systemctl start mysqld
linux$:] systemctl enable mysqld
linux$:] grep "temporary password is generated" /var/log/mysqld.log
linux$:] mysql -uroot -p
Mysql 5.7.6以后的版本用下面的命令进行账号密码初始化SQL>ALTER USER USER() IDENTIFIED BY 'Twcx@2023';SQL>FLUSH PRIVILEGES;
linux$:] systemctl restart mysqld
linux$:] ystemctl enable mysqld

2、Hive安装

linux$:] cd /soft
linux$:] wget https://mirrors.tuna.tsinghua.edu.cn/apache/hive/hive-3.1.3/apache-hive-3.1.3-bin.tar.gz
linux$:] tar -zxvf apache-hive-3.1.3-bin.tar.gz
linux$:] mv apache-hive-3.1.3-bin hive
linux$:] cd /soft/hive/conf
linux$:] mv hive-env.sh.template  hive-env.sh
linux$:] echo '' > hive-env.sh
linux$:] mv hive-default.xml.template  hive-site.xml
linux$:] echo '' > hive-site.xml解决hadoop与hive包之间jar冲突的问题
linux$:] cd /soft/hive/lib
linux$:] rm -rf guava-19.0.jar
linux$:] cp /soft/hadoop/share/hadoop/common/lib/guava-27.0-jre.jar ./解决Mysql 关联，依赖包
mysql驱动下载地址
https://dev.mysql.com/downloads/connector/j/
mysql 8.0驱动下载地址
linux$:] wget https://downloads.mysql.com/archives/get/p/3/file/mysql-connector-java-8.0.11.tar.gz
linux$:] tar -zxvf mysql-connector-java-8.0.11.tar.gz
linux$:] cd mysql-connector-java-8.0.11
linux$:] cp mysql-connector-java-8.0.11.jar  /soft/hive/lib/mysql 5.7驱动下载地址[当前用的此驱动]
linux$:] wget https://repo1.maven.org/maven2/mysql/mysql-connector-java/6.0.6/mysql-connector-java-6.0.6.jar
linux$:] cp mysql-connector-java-6.0.6.jar  /soft/hive/lib/

3、Hive配置

配置文件
linux$:] vi /soft/hive/conf/hive-env.sh
export HADOOP_HOME=/soft/hadoop
export HIVE_CONF_DIR=/soft/hive/conf
export HIVE_AUX_JARS_PATH=/soft/hive/lib配置日志文件，可以更改级别为DEBUG，用于调试
linux$:] vi /soft/hive/conf/hive-log4j2.properties
linux$:] cp hive-log4j2.properties.template hive-log4j2.properties
linux$:] vi hive-log4j2.properties
property.hive.log.dir = /user/hive/log配置文件:
注意：配置mysql访问的时候，就算是指定了字符集，mysql初始化时的字符集依然为latin
linux$:] vi /soft/hive/conf/hive-site.xml<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<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&amp;useSSL=false</value></property><property><name>javax.jdo.option.ConnectionDriverName</name><value>com.mysql.cj.jdbc.Driver</value></property><property><name>javax.jdo.option.ConnectionUserName</name><value>pyroot</value></property><property><name>javax.jdo.option.ConnectionPassword</name><value>Twcx@2023</value></property><property><name>hive.metastore.uris</name><value>thrift://Master:9083</value></property><property><name>hive.metastore.event.db.notification.api.auth</name><value>false</value></property><property><name>hive.metastore.schema.verification</name><value>false</value></property><property><name>hive.server2.thrift.bind.host</name><value>Master</value></property><property><name>hive.server2.thrift.port</name><value>10000</value></property><property><name>hive.cli.print.header</name><value>true</value></property><property><name>hive.cli.print.current.db</name><value>true</value></property><property><name>beeline.hs2.connection.user</name><value>root</value></property><property><name>beeline.hs2.connection.password</name><value>root</value></property>
</configuration>

4、启动Hive
说明：
命令行客户端：
bin/hive 不推荐使用，是shell客户端
bin/beeline
强烈推荐使用，是jdbc的客户端，可以在嵌入式与远程客户端使用，且访问的hiveServer2,通过hiveServer2访问metastore，再Hive mysql数据。
HiveServer2支持多客户端的并发和身份证认证，旨在为开发API客户端如JDBC,ODBC提供更好的支持

重启hdfs
linux$:] stop-all.sh
linux$:] start-all.sh初始化hive元数据信息到mysql中
linux$:] schematool -dbType mysql -initSchema  #初始化schema检查mysql是否存在hive库，hive库的74张表
linux$:] mysql -uroot -pSQL> show databases;SQL> use hiveSQL> show tables;启动metastore
linux$:] mkdir -p /soft/hive/metastorelog
linux$:] cd /soft/hive/metastorelog
linux$:] nohup hive --service metastore --hiveconf hive.root.logger=DEBUG,console &启动hiveserver2
linux$:] mkdir -p /soft/hive/hiveserver2log
linux$:] cd /soft/hive/hiveserver2log
linux$:] nohup $HIVE_HOME/bin/hive --service hiveserver2 &

5、远程测试metastore与hiveserver2【可在Datanode主机上搭建客户端】

安装Hive软件
linux$:] cd /soft
linux$:] wget https://mirrors.tuna.tsinghua.edu.cn/apache/hive/hive-3.1.3/apache-hive-3.1.3-bin.tar.gz
linux$:] tar -zxvf apache-hive-3.1.3-bin.tar.gz
linux$:] mv apache-hive-3.1.3-bin hive解决hadoop与hive包之间jar冲突的问题
linux$:] cd /soft/hive/lib
linux$:] rm -rf guava-19.0.jar
linux$:] cp /soft/hadoop/share/hadoop/common/lib/guava-27.0-jre.jar ./驱动部署，远程可不需要
linux$:] wget https://repo1.maven.org/maven2/mysql/mysql-connector-java/6.0.6/mysql-connector-java-6.0.6.jar
linux$:] cp mysql-connector-java-6.0.6.jar  /soft/hive/lib/配置Hive文件
配置文件
linux$:] vi /soft/hive/conf/hive-env.sh
export HADOOP_HOME=/soft/hadoop
export HIVE_CONF_DIR=/soft/hive/conf
export HIVE_AUX_JARS_PATH=/soft/hive/lib配置文件
linux$:] vi /soft/hive/conf/hive-site.xml
<configuration><property><name>hive.metastore.warehouse.dir</name><value>/user/hive/warehouse</value></property><property><name>hive.metastore.uris</name><value>thrift://Master:9083</value></property>
</configuration>测试metastore，不加主机与IP，默认是访问的metastore的暴露端口 9083
linux$:] beeline -u jdbc:hive2://
> show databases;测试hiveserver2，端口10000，是访问的是hiverserver2的暴露端口
linux$:] beeline -u jdbc:hive2://Master:10000
> show databases;其它测试：
win 环境，下载DBeaver,通过10000号进行访问链接。账号默认为hive,密码为空或者填入hive。
