安装

tar -zxvf apache-hive-3.1.3-bin.tar.gz 

docker cp /home/apache-hive-3.1.3-bin/ hadoop_master:/usr/local/

rm -rf /usr/local/apache-hive-3.1.3-bin/lib/guava-19.0.jar

cp /usr/local/hadoop-3.3.6/share/hadoop/common/lib/guava-27.0-jre.jar /usr/local/apache-hive-3.1.3-bin/lib/

修改配置文件

cd /usr/local/apache-hive-3.1.3-bin/conf
cp hive-env.sh.template hive-env.sh

vi hive-env.sh

export HADOOP_HOME=/usr/local/hadoop-3.3.6
export HIVE_CONF_DIR=/usr/local/apache-hive-3.1.3-bin/conf

mysql jdbc驱动

## 驱动下载
https://downloads.mysql.com/archives/c-j/

## 下载 rpm 包 并安装
rpm -ivh 报名
## 查看驱动位置
rpm -ql 包名

## zip包
docker cp /home/mysql-connector-java-5.1.49/mysql-connector-java-5.1.49.jar hadoop_master:/usr/local/apache-hive-3.1.3-bin/lib/
cd /usr/local/apache-hive-3.1.3-bin/bin

初始化元数据

cd /usr/local/apache-hive-3.1.3-bin/bin 
./schematool -initSchema -dbType mysql -verbos
#初始化成功会在mysql中创建74张表

在hdfs创建hive存储目录

hadoop fs -mkdir /tmp
hadoop fs -mkdir -p /user/hive/warehouse
hadoop fs -chmod g+w /tmp
hadoop fs -chmod g+w /user/hive/warehouse

1.启动metastore服务 
#前台启动 关闭ctrl+c

/usr/local/apache-hive-3.1.3-bin/bin/hive --service metastore

#前台启动开启debug日志

/usr/local/apache-hive-3.1.3-bin/bin/hive --service metastore --hiveconf hive.root.logger=DEBUG,console

#后台启动 进程挂起  关闭使用jps+kill -9 

nohup /usr/local/apache-hive-3.1.3-bin/bin/hive --service metastore &

2.启动hiveserver2服务

nohup /usr/local/apache-hive-3.1.3-bin/bin/hive --service hiveserver2 &

#注意 启动hiveserver2需要一定时间 不要启动之后立即beeline连接 可能连接不上

3.beeline 客户端连接
## 拷贝master安装包到beeline客户端机器上（slave2）
scp -r /usr/local/apache-hive-3.1.3-bin/ root@slave2:/usr/local/
## 连接访问
ssh slave2
/usr/local/apache-hive-3.1.3-bin/bin/beeline
beeline> ! connect jdbc:hive2://master:10000
beeline> root
beeline> 直接回车不要密码
