Hive環境搭建及簡單使用

前言：

• 上篇文章我們介紹了Hive源碼編譯的相關內容，本篇文章將主要介紹Hive環境的搭建步驟及簡單使用。

1.下載安裝包并解壓

# 下載地址http://archive.cloudera.com/cdh6/cdh/5/ 選擇hive-1.1.0-cdh6.7.0.tar.gz包，也可用我們上篇文章編譯來的包
[hadoop@hadoop000 ~]$ ll
total 32
drwxrwxr-x 4 hadoop hadoop 4096 Jun  1 21:27 app          --軟件安裝路徑
drwx------ 3 hadoop hadoop 4096 Jun  1 21:46 data
drwxrwxr-x 2 hadoop hadoop 4096 May 31 19:41 lib
drwxrwxr-x 2 hadoop hadoop 4096 May 31 19:41 maven_repo
drwxrwxr-x 2 hadoop hadoop 4096 Jun  1 21:46 pids
drwxrwxr-x 2 hadoop hadoop 4096 May 31 19:42 shell
drwxrwxr-x 2 hadoop hadoop 4096 May 31 19:48 software     --安裝包路徑
drwxrwxr-x 3 hadoop hadoop 4096 May 31 20:59 source       --源碼包路徑
[hadoop@hadoop000 ~]$ cd software/
[hadoop@hadoop000 software]$ pwd
/home/hadoop/software
[hadoop@hadoop000 software]$ wget http://archive.cloudera.com/cdh6/cdh/5/hive-1.1.0-cdh6.7.0.tar.gz
[hadoop@hadoop000 software]$ tar -xzvf hive-1.1.0-cdh6.7.0.tar.gz -C /home/hadoop/app/

2.配置環境變量

[hadoop@oradb3 ~]$ vi .bash_profile
# 添加下面內容：
export HIVE_HOME=/home/hadoop/app/hive-1.1.0-cdh6.7.0
export PATH=$HIVE_HOME/bin:$PATH
[hadoop@oradb3 ~]$ source .bash_profile
# 或添加到全局環境變量/etc/profile也可以

3.配置文件修改

[hadoop@hadoop000 conf]$ pwd
/home/hadoop/app/hive-1.1.0-cdh6.7.0/conf
[hadoop@hadoop000 conf]$ cp hive-env.sh.template  hive-env.sh
[hadoop@hadoop000 conf]$ vi hive-env.sh
# 更改HADOOP_HOME
HADOOP_HOME=/home/hadoop/app/hadoop-2.6.0-cdh6.7.0
[hadoop@hadoop000 conf]$ vi hive-site.xml
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>

<configuration>
        <property>
                <name>javax.jdo.option.ConnectionURL</name>
                <value>jdbc:mysql://localhost:3306/ruozedata_basic03?createDatabaseIfNotExist=true</value>
        </property>
        <property>
                <name>javax.jdo.option.ConnectionDriverName</name>
                <value>com.mysql.jdbc.Driver</value>
        </property>
        <property>
                <name>javax.jdo.option.ConnectionUserName</name>
                <value>root</value>
        </property>
        <property>
                <name>javax.jdo.option.ConnectionPassword</name>
                <value>123456</value>
        </property>
</configuration>

4.在lib下添加MySQL驅動包

# 需要自行下載 下載地址https://dev.mysql.com/downloads/connector/j/
[hadoop@oradb3 lib]$ pwd
/home/hadoop/app/hive-1.1.0-cdh6.7.0/lib
[hadoop@oradb3 lib]$ ll mysql-connector-java-5.1.13-bin.jar
-rw-r--r-- 1 hadoop hadoop 767492 Jun  1 22:01 mysql-connector-java-5.1.13-bin.jar

5.創建表進行測試

[hadoop@oradb3 ~]$ hive
which: no hbase in (/home/hadoop/app/hive-1.1.0-cdh6.7.0/bin:/home/hadoop/app/hadoop-2.6.0-cdh6.7.0/bin:/usr/java/jdk1.7/bin:/usr/lib64/qt-3.3/bin:/usr/local/bin:/bin:/usr/bin)

Logging initialized using configuration in jar:file:/home/hadoop/app/hive-1.1.0-cdh6.7.0/lib/hive-common-1.1.0-cdh6.7.0.jar!/hive-log4j.properties
hive> create database ruoze;
