[大数据]Hive3.1.2从安装变提数机

解压安装

tar zxvf apache-hive-3.1.2-bin.tar.gz -C /opt/module/

配置环境变量

echo 'export HIVE_HOME=/opt/module/apache-hive-3.1.2-bin' >> /etc/profile
echo 'export PATH=$PATH:$HIVE_HOME/bin' >> /etc/profile

# 读取环境变量
source /etc/profile

初始化derby元数据

bin/schematool -dbType derby -initSchema

#报错
[root@node01 software]# /opt/module/apache-hive-3.1.2-bin/bin/schematool -dbType derby -initSchema

解决jar包问题

mv $HIVE_HOME/lib/log4j-slf4j-impl-2.10.0.jar $HIVE_HOME/lib/log4j-slf4j-impl-2.10.0.jar.bak

cp $HADOOP_HOME/share/hadoop/common/lib/guava-27.0-jre.jar $HIVE_HOME/lib/
mv $HIVE_HOME/lib/guava-19.0.jar $HIVE_HOME/lib/guava-19.0.jar.bak

启动Hive

#先启动zookeeper和hadoopHA

#执行hive启动命令
hive

MySQL存储元数据

• 安装配置MySQL5.7

#卸载mariadb
rpm -qa|grep mariadb
rpm -e --nodeps 文件名
rpm -e --nodeps  mariadb-libs-5.5.68-1.el7.x86_64

#解压
tar xvf mysql-5.7.32-1.el7.x86_64.rpm-bundle.tar
#安装
rpm -ivh mysql-community-common-5.7.32-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-5.7.32-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-compat-5.7.32-1.el7.x86_64.rpm
rpm -ivh mysql-community-devel-5.7.32-1.el7.x86_64.rpm
rpm -ivh mysql-community-client-5.7.32-1.el7.x86_64.rpm
rpm -ivh mysql-community-server-5.7.32-1.el7.x86_64.rpm

#启动
systemctl start mysqld
systemctl enable mysqld

#查看临时密码
grep 'temporary password' /var/log/mysqld.log

#登录MySQL
mysql -uroot -p'临时密码'

#修改密码强度策略
set global validate_password_length=4;
set global validate_password_policy=0;

#修改密码
set password=password('000000');

修改mysql root用户的登录权限
update mysql.user set Host='%' where HOST='localhost' and User='root';

#创建hive元数据库
CREATE DATABASE hive DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;

#授权
grant all on hive.* to 'hive'@'%' identified by '000000';

#刷新权限
flush privileges; 

#上传node01配置mysql驱动包
cp mysql-connector-java-5.1.47.jar /opt/module/apache-hive-3.1.2-bin/lib

配置hive-core.xml

初始化MySQL元数据库

schematool -initSchema -dbType mysql -verbose

jdbc方式连接Hive

# 启动元数据服务
hive --service metastore

# 启动hiveserver2
hive --service hiveserver2

# jdbc连接hive
beeline -u jdbc:hive2://node01:10000 -n root


#报错
[root@node01 conf]# beeline -u jdbc:hive2://node01:10000 -n root

#修改hadoop的core-site.xml
<property>
	<name>hadoop.proxyuser.root.hosts</name>
	<value>*</value>
</property>
<property>
	<name>hadoop.proxyuser.root.groups</name>

再将RunJar进程杀死，重启集群就解决问题了
kill -9 pid
