Hive 2.1.1安装文档

一环境

OS:ubuntu 16.04.3 LTS
Hadoop:2.6.5
java:1.8.0_151
Hive 2.1.1

Hadoop集群环境

10.190.3.10     master
10.190.3.6      slave

二安装

2.1 配置环境变量

HIVE_HOME=/home/hadoop/apache-hive-2.1.1-bin
PATH=$PATH:$HIVE_HOME/bin
export HIVE_NAME PATH

2.2 Metastore

metastore是Hive元数据集中存放地。它包括两部分：服务和后台数据存储。有三种方式配置metastore：内嵌metastore、本地metastore以及远程metastore。
本次搭建中采用MySQL作为远程仓库，部署在master节点上，hive服务端也安装在master上，hive客户端即slave访问hive服务器。

2.3 Mysql安装

sudo apt install mysql-server

2.3.1 编辑/etc/mysql/mysqld.conf.d/mysqld.cnf

bind-address            = 10.190.3.10

完成后重启mysql

sudo service mysql restart

2.3.2 创建hive用户并且可以赋予hive远程登录的权限

mysql -u root -p
CREATE USER 'hive' IDENTIFIED BY 'hive';
GRANT ALL PRIVILEGES ON *.* TO 'hive'@'%' WITH GRANT OPTION;
flush privileges;

2.3.3 创建hive数据库

mysql -uroot -p
create database hive

2.4 配置Hive

进入到hive的配置文件目录下，找到hive-default.xml.template，cp份为hive-default.xml
另创建hive-site.xml并添加参数


 
 

     
         javax.jdo.option.ConnectionURL
         jdbc:mysql://10.190.3.10:3306/hive?createDatabaseIfNotExist=true
     


     
         javax.jdo.option.ConnectionDriverName
         com.mysql.jdbc.Driver
     

     
         javax.jdo.option.ConnectionUserName
         hive
     

     
         javax.jdo.option.ConnectionPassword
         hive
     


   hive.metastore.schema.verification
   false
    
    Enforce metastore schema version consistency.
    True: Verify that version information stored in metastore matches with one from Hive jars.  Also disable automatic
          schema migration attempt. Users are required to manully 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.

2.5 JDBC下载

cp mysql-connector-java-5.1.45-bin.jar apache-hive-2.1.1-bin/lib/

2.6 Hive客户端配置

 scp -r apache-hive-1.2.1-bin/ hadoop@slave:/home/hadoop
 #登录slave机器
 vi hive-site.xml
 
 
 
 

  hive.metastore.uris
  thrift://10.190.3.10:9083
  Thrift uri for the remote metastore. Used by metastore client to connect to remote metastore.

2.7 Hive启动

schematool -dbType mysql -initSchema --verbose      #mysql元数据库初始化
hive --service metastore &
jps
10288 RunJar  #多了一个进程
9365 NameNode
9670 SecondaryNameNode
11096 Jps
9944 NodeManager
9838 ResourceManager
9471 DataNode

Hive服务器端即master访问

hive

Hive客户端即slave访问
