centos7 Hive2.3.6安装与配置_hive 2.3.6 单机安装

一.简介

• Hive 由 Facebook 实现并开源，是基于 Hadoop 的一个数据仓库工具，可以将结构化的数据映射为一张数据库表，并提供 HQL(Hive SQL)查询功能，底层数据是存储在 HDFS 上。
• Hive 本质: 将 SQL 语句转换为 MapReduce 任务运行，使不熟悉 MapReduce 的用户很方便地利用 HQL 处理和计算 HDFS 上的结构化的数据,是一款基于 HDFS 的 MapReduce 计算框架
主要用途：用来做离线数据分析，比直接用 MapReduce 开发效率更高。

二.安装与配置

基于<<Hadoop2.7.7 HA完全分布式集群搭建>>

1.下载 Hive2.3.6

cd /usr/local
wget https://mirrors.tuna.tsinghua.edu.cn/apache/hive/hive-2.3.6/apache-hive-2.3.6-bin.tar.gz

tar -zxvf apache-hive-2.3.6-bin.tar.gz

2.配置hive环境变量

# 编辑 /etc/profile 文件, 在其中添加以下内容 
vim /etc/profile
export HIVE_HOME=/usr/local/apache-hive-2.3.6-bin
export PATH=$PATH:$HIVE_HOME/bin

# 激活配置
source /etc/profile

3.在hadoop下创建hive所用文件夹

$HADOOP_HOME/bin/hadoop fs -mkdir  -p     /usr/local/apache-hive-2.3.6/tmp
$HADOOP_HOME/bin/hadoop fs -mkdir  -p     /usr/local/apache-hive-2.3.6/warehouse
$HADOOP_HOME/bin/hadoop fs -chmod g+w   /usr/local/apache-hive-2.3.6/tmp
$HADOOP_HOME/bin/hadoop fs -chmod g+w   /usr/local/apache-hive-2.3.6/warehouse

4.下载对应的mysql连接jar

https://dev.mysql.com/doc/connector-j/5.1/en/connector-j-versions.html
https://dev.mysql.com/downloads/connector/j/

将目标文件移动到 hive的lib文件夹下

mv mysql-connector-java-5.1.48.jar $HIVE_HOME/lib

创建数据库,配置用户和权限

create database metastore;
grant all on metastore.* to hive@'%'  identified by 'hive';
grant all on metastore.* to hive@'localhost'  identified by 'hive';
flush privileges;

5.配置 Hive

cd apache-hive-2.3.6-bin/conf/
cp hive-env.sh.template hive-env.sh 
cp hive-default.xml.template hive-site.xml 
cp hive-log4j2.properties.template hive-log4j2.properties 
cp hive-exec-log4j2.properties.template hive-exec-log4j2.properties
