1、下载安装包：apache-hive-3.1.1-bin.tar.gz

上传至linux系统/usr/local/soft/路径

2、解压软件

cd /usr/local/soft/

tar -zxvf apache-hive-3.1.1-bin.tar.gz

3、修改系统环境变量

vim /etc/profile

添加内容：

export HIVE_HOME=/usr/local/soft/apache-hive-3.1.1-bin

export PATH=$PATH:$HADOOP_HOME/sbin:$HIVE_HOME/bin

保存：

source /etc/profile

4、修改hive环境变量

cd /usr/local/soft/apache-hive-3.1.1-bin/bin/

编辑hive-config.sh文件

vi hive-config.sh

新增内容：

export JAVA_HOME=/usr/local/soft/jdk1.8.0_11

export HIVE_HOME=/usr/local/soft/apache-hive-3.1.1-bin

export HADOOP_HOME=/usr/local/soft/hadoop-3.2.0

export HIVE_CONF_DIR=/usr/local/soft/apache-hive-3.1.1-bin/conf

5、拷贝hive配置文件

cd /usr/local/soft/apache-hive-3.1.1-bin/conf/

cp hive-default.xml.template hive-site.xml

6、修改Hive配置文件,找到对应的位置进行修改

<property>

    <description>

      JDBC connect string for a JDBC metastore.

      To use SSL to encrypt/authenticate the connection, provide database-specific SSL flag in the connection URL.

  </property>

  <property>

    <name>datanucleus.schema.autoCreateAll</name>

    <value>true</value>

    <description>Auto creates necessary schema on a startup if one doesn't exist. Set this to false, after creating it once.To enable auto create also set hive.metastore.schema.verification=false. Auto creation is not recommended for production use cases, run schematool command instead.</description>

  </property>

<property>

    <name>hive.metastore.schema.verification</name>

    <value>false</value>

    <description>

      Enforce metastore schema version consistency.

      True: Verify that version information stored in is compatible with one from Hive jars. Also disable automatic

            schema migration attempt. Users are required to manually migrate schema after Hive upgrade which ensures

            proper metastore schema migration. (Default)

      False: Warn if the version information stored in metastore doesn't match with one from in Hive jars.
