克隆出lwm102、lwm103
以lwm102为例
vi /etc/sysconfig/network-scripts/ifcfg-ens33把IP地址101改为102
service network restart
把lwm102连接CRT操作
sed -i '/UUID=/cUUID='`uuidgen`'' /etc/sysconfig/network-scripts/ifcfg-ens33
hostnamectl set-hostname lwm102
cd /opt/data/zookeeper/zkdata
echo 2 > myid
source /etc/profile
lwm103重复以上克隆步骤（绿色的对应修改）
在lwm101操作
rpm -qa | grep openssh
service sshd status
ssh-keygen -t rsa
ssh-copy-id lwm101
ssh-copy-id lwm102
ssh-copy-id lwm103
分别在lwm101、lwm102、lwm103输入以下命令
systemctl stop firewalld.service
systemctl disable firewalld.service
zkServer.sh start
hadoop-daemon.sh start journalnode
在lwm101操作
hdfs namenode -format
hdfs zkfc -formatZK
scp -r /opt/data/hadoop/namenode/ root@lwm102:/opt/data/hadoop/
start-dfs.sh
start-yarn.sh
分别在lwm101、lwm102、lwm103执行jps查看

新建一个lwm101窗口：
cd /opt/m/apache-hive-2.3.7-bin
bin/beeline
在lwm102：
tar -zxvf /opt/w/apache-hive-2.3.7-bin.tar.gz -C /opt/m/
cd /opt/m/apache-hive-2.3.7-bin/conf/
touch hive-site.xml
Scp -r hive-site.xml root@lwm101:/opt/m/apache-hive-2.3.7-bin/conf
Source /etc/profile
beeline -u jdbc:hive2://lwm101:10000 -n root -p
输入1qaz@WSX显示下面则成功
