1.基本信息
| 版本 | 1.2.1 |
|---|---|
| 安装机器 | 三台机器 |
| 账号 | hadoop |
| 源路径 | /opt/software/apache-hive-1.2.1-bin.tar.gz |
| 目标路径 | /opt/hive -> opt/apache-hive-1.2.1-bin/ |
| 依赖关系 | mysql |
2.安装过程
1).登陆172.24.5.173，并登陆mysql，创建hive元数据库及hive用户,并设置字符集为latin1：
[root
@bgs
-5p173-wangwenting ~]# mysql -u root -p
mysql>create database hive_metastore;
mysql>GRANT ALL PRIVILEGES ON hive_metastore.* TO
'hive'
@
'%'
IDENTIFIED BY
'hive'
;
mysql>GRANT ALL PRIVILEGES ON hive_metastore.* TO
'hive'
@bgs
-5p173-wangwenting IDENTIFIED BY
'hive'
;
mysql>flush privileges;
mysql>alter database hive_metastore character set latin1;
|
2).创建hadoop目录，并修改权限：
[root
@bgs
-5p173-wangwenting ~]# su - hadoop
[hadoop
@bgs
-5p173-wangwenting ~]$ hadoop fs -mkdir -p /user/hive/warehouse
[hadoop
@bgs
-5p173-wangwenting ~]$ hadoop fs -chmod
777
/tmp
[hadoop
@bgs
-5p173-wangwenting ~]$ hadoop fs -chmod
777
/user/hive/warehouse
|
3).将apache-hive-${version}-bin.tar.gz通过tar -zxvf命令解压缩至目的安装目录,并设置软连接:
[hadoop
@bgs
-5p173-wangwenting ~]$ cd /opt/software
[hadoop
@bgs
-5p173-wangwenting software]$ tar -zxvf apache-hive-${version}-bin.tar.gz -C /opt
[hadoop
@bgs
-5p173-wangwenting software]$ cd /opt
[hadoop
@bgs
-5p173-wangwenting opt]$ ln -s /opt/apache-hive-${version}-bin /opt/hive
|
4).删除hadoop目录中的jline-0.9.94.jar,防止jar冲突（若存在）:
[hadoop
@bgs
-5p173-wangwenting hive]$ rm -r /opt/hadoop/share/hadoop/yarn/lib/jline-
0.9
.
94
.jar
在/opt/hadoop/hive/conf目录下添加hive-site.xml,并修改hive-site.xml配置文件:
[hadoop
@bgs
-5p173-wangwenting hive]$ cd /opt/hive/conf
[hadoop
@bgs
-5p173-wangwenting conf]$ cp hive-
default
.xml.template hive-site.xml
[hadoop
@bgs
-5p173-wangwenting conf]$ vim hive-site.xml
添加下面内容:（可以将里面的内容全部删除只添加以下内容，我的是追加的形式，不过要修改里面的配置内容。${system-user.name}的值改为hive,${java.io.tmpdir }改为/tmp）
<configuration>
<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql:
//bgs-5p173-wangwenting:3306/hive_metastore?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>hive</value>
</property>
<property>
<name>javax.jdo.option.ConnectionPassword</name>
<value>hive</value>
</property>
<property>
<name>hive.metastore.warehouse.dir</name>
<value>/user/hive/warehouse</value>
</property>
<property>
<name>hive.querylog.location</name>
<value>/tmp/hive</value>
</property>
<property>
<name>hive.server2.logging.operation.log.location</name>
<value>/tmp/hive/operation_logs</value>
</property>
<property>
<name>hive.exec.scratchdir</name>
<value>/tmp/hive</value>
</property>
</configuration>
|
6).确保启动hadoop集群的情况下，切换到hadoop账户
[hadoop
@bgs
-5p173-wangwenting conf]$ nohup /opt/hive/bin/hive &
|
7).启动hiveserver2：
[hadoop
@bgs
-5p173-wangwenting conf]$ nohup /opt/hive/bin/hive --service hiveserver2 &
|
使用beeline工具连接到thrift server
[hadoop
@bgs
-5p173-wangwenting conf]$ /opt/hive/bin/beeline -u jdbc:hive2:
//bgs-5p173-wangwenting:10000
|
如果连接失败需要拷贝一个jar包到lib目录下mysql-connector-java-5.1.35-bin.jar
8).测试hive基本命令是否正常运行:
hive> create table test(a
int
);
OK
Time taken:
0.55
seconds
hive> show tables;
OK
Test
Time taken:
0.031
seconds, Fetched:
1
row(s)
hive> desc test;
OK
a
int
Time taken:
0.157
seconds, Fetched:
1
row(s)
hive> select a from test;
OK
Time taken:
0.14
seconds
hive> drop table test;
OK
Time taken:
0.671
seconds
hive> show tables;
OK
Time taken:
0.032
seconds
|
如果测试同上，则说明hive安装成功，能够正常运行。
如果报错，需要修改conf目录下的hive-site.xml文件，将${system:user.name} 换成hive即可
