ubuntu16.04 安装hive及配置
1.下载hive
http://mirror.bit.edu.cn/apache/hive/
2.解压文件
tar -xvf apache-hive-3.1.2-bin.tar.gz
修改名称
mv apache-hive-3.1.2 hive
3.配置环境变量
1.修改~/.bashrc文件
vim ~/.bashrc
添加
export HIVE_HOME=/home/user/server/hive export PATH=$PATH:$HIVE_HOME/bin
//立即生效source ~/.bashrc
2.修改hive-site.xml
//新建文件 cp hive-default.xml.template hive-default.xml //新建文件 touch hive-site.xml
在hive-site.xml中添加<?xml version="1.0" encoding="UTF-8" standalone="no"?><?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql://localhost:3306/hive?createDatabaseIfNotExist=true</value>
<description>JDBC connect string for a JDBC metastore</description>
</property>
<property>
<name>javax.jdo.option.ConnectionDriverName</name>
<value>com.mysql.jdbc.Driver</value>
<description>Driver class name for a JDBC metastore</description>
</property>
<!--数据库用户-->
<property>
<name>javax.jdo.option.ConnectionUserName</name>
<value>root</value>
<description>username to use against metastore database</description>
</property>
<!--数据库密码-->
<property>
<name>javax.jdo.option.ConnectionPassword</name>
<value>hive</value>
<description>password to use against metastore database</description>
</property>
</configuration>
4.在mysql中添加database
mysql -uroot -p //输入密码进入 create database hive;
5.启动hadoop和hive
//启动hadoopbash start-all.sh //启动hive./hive
6.问题处理
1.启动hive时
Cannot find hadoop installation: $HADOOP_HOME or $HADOOP_PREFIX must be set or hadoop must be in the path
处理:
在confi目录下
cp hive-env.sh.template hive-env.sh
在hive-env.sh添加
export HADOOP_HOME=/home/user/server/hadoop/hadoop-3.2.1
2.报错

/home/tjtl/user/hive/lib
/home/tjtl/user/hadoop/hadoop-3.2.1/share/hadoop/common/lib
两个目录下 guava jar包的版本,删除低版本，复制高版本
rm guava-19.0.jar cp ../../hadoop/hadoop-3.2.1/share/hadoop/common/lib/guava-27.0-jre.jar ./
