hive分布式安装部署
hive的安装与部署
开始本次操作前，确保Hadoop和zk顺利启动。
如图所示，mysql server应安装在node2节点上，Hiver Client 安装在了
master 节点，MySql Server 安装在 node2 节点。
本次安装需要如下的安装包:
mysql-connector-java-5.1.5-bin.jar
apache-hive-2.3.7-bin.tar
首先在node2节点配置。
将mysql-connector-java-5.1.5-bin.jar传输到node2节点。
1.安装数据库（使用离线源）
[root@node2 ~]# yum -y install mariadb-server
2、启动mysql服务，并设置开机自启
[root@node2 ~]# systemctl start mariadb
[root@node2 ~]# systemctl enable mariadb
3、初始化mysql并设置密码并测试登陆mysql
[root@node2 ~]# mysql_secure_installation
**这里我的密码设置为000000。
4.登录数据库并且创建用户
[root@node2 ~]# mysql -u root -p000000
创建用户：
create user ‘root’@’%’ identified by ‘000000’;
允许远程连接：
grant all privileges on . to ‘root’@’%’ with grant option;
刷新权限：
flush privileges;
5、Node2将jar包发给node1
[root@node2 ~]# scp mysql-connector-java-5.1.5-bin.jar node1:/root
二、在master和node1节点配置
1、传输tar包到master节点
使用SecureFX进行传输
2、Master解压hive压缩包，并将解压后的文件输给node1
root@master ~]# tar -zxvf apache-hive-2.3.7-bin.tar.gz
[root@master ~]# scp apache-hive-2.3.7-bin node1:/root
3.修改环境变量（master和node1）
[root@master ~]# vi /etc/profile
[root@node1 ~]# vi /etc/profile
添加：
export HIVE_HOME=/root/apache-hive-2.3.7-bin export PATH=$PATH:$HIVE_HOME/bin验证环境变量：
[root@master ~]# source /etc/profile
[root@node1 ~]# source /etc/profile
4.mater配置客户端
更换jar包
[root@master ~]# cp /root/apache-hive-2.3.7-bin/lib/jline-2.12.jar /opt/bigdata/hadoop-3.0.0/lib
5、添加hive-site.xml
[root@master ~]# cd /usr/hive/apache-hive-2.3.7-bin/conf
[root@master conf]# vi hive-site.xml
hive.metastore.warehouse.dir
/user/hive_remote/warehouse
hive.metastore.local
false
hive.metastore.uris
thrift://node1:9083
6.在node1节点将jar包复制到lib中
[root@node1 ~]# cp mysql-connector-java-5.1.5-bin.jar apache-hive-2.3.7-bin/lib/
node1复制配置文件以及配置
[root@node1 ~]# cd /usr/hive/apache-hive-2.3.7-bin/conf
[root@node1 conf]# cp hive-env.sh.template hive-env.sh
在hive-env.sh添加：
HADOOP_HOME=/opt/bigdata/hadoop-3.0.0/（根据自己的真实路径来）
创建 hive-site.xml 文件
[root@node1 conf]# vi hive-site.xml
hive.metastore.warehouse.dir
/user/hive_remote/warehouse
javax.jdo.option.ConnectionURL
jdbc:mysql://node2:3306/hive?createDatabaseIfNotExist=true
javax.jdo.option.ConnectionDriverName
com.mysql.jdbc.Driver
javax.jdo.option.ConnectionUserName
root
javax.jdo.option.ConnectionPassword
000000
hive.metastore.schema.verification
false
datanucleus.schema.autoCreateAll
true
启动hive，并进行测试操作（查看数据库）
[root@node1 ~]cd /usr/hive/apache-hive-2.3.7-bin/
[root@node1 apache-hive-2.3.7-bin]bin/hive
which: no hbase in (/opt/bigdata/hadoop-3.0.0/bin:/opt/bigdata/hadoop-3.0.0/sbin:/opt/bigdata/jdk1.8.0_161/bin:/root/zookeeper-3.4.14/bin:/opt/bigdata/hadoop-3.0.0/bin:/opt/bigdata/hadoop-3.0.0/sbin:/opt/bigdata/jdk1.8.0_161/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/apache-hive-2.3.7-bin/bin:/root/bin:/root/apache-hive-2.3.7-bin/bin)

Hive-on-MR is deprecated in Hive 2 and may not be available in the future versions. Consider using a different execution engine (i.e. spark, tez) or using Hive 1.X releases.
