After downloading, upload it to the /opt/install folder of the linux virtual machine

2. Unzip hive and configure environment variables

Go to the install directory (the install folder is a custom folder we use to store the installation package)

cd /opt/install

decompress hive 

tar -zxf ./apache-hive-3.1.2-bin.tar.gz -C /opt/soft/

rename the folder

mv ./apache-hive-3.1.2-bin/ hive312

Configure environment variables

vim /etc/profile

#hive
export HIVE_HOME=/opt/soft/hive312
export PATH=$HIVE_HOME/bin:$PATH

Three configuration files for configuring hive

The following commands are run under the conf folder

cd /opt/soft/hive312/conf

Change hive-default.xml.template to hive-default.xml

mv hive-default.xml.template hive-default.xml

Configure hive-site.xml (create a new file)

vim ./hive-site.xml

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>

Copy the driver of mysql8 to the /opt/soft/hive312/lib directory

cp /opt/install/mysql-connector-java-8.0.29.jar /opt/soft/hive312/lib

Four update guava

The following commands are executed in the hive312/lib directory

cd /opt/soft/hive312/lib/

Delete the guava file in this directory

rm -rf ./guava-19.0.jar 

Copy the guava file in hadoop

cp /opt/soft/hadoop313/share/hadoop/common/lib/guava-27.0-jre.jar ./

look at the file again 

find ./ -name guava*

Five hive initialization

Hadoop, mysql services must be started

initialization command

schematool -dbType mysql -initSchema

Enter hive to see if the installation is successful

hive

Appears similar to even if successful

hive (default)> 

Create a database try

hive (default)> show databases;
OK
database_name
default

创建数据库
hive (default)> create database kb23DB;

退出数据库
hive (default)> quit

Six open remote connection

cd /opt/soft/hive312

It is normal for some warnings to appear in the following commands 

metadata service

nohup hive --service metastore &

hive remote service

nohup hive --service hiveserver2 &

Connect to hive service through beeline

beeline -u jdbc:hive2://localhost:10000

Seven use datagrip to connect to hive

After completing the above steps, you can use datagrip to connect to hive

There is no need to write the user name and password here, they are all empty
