centos7 hive + 远程mysql 搭建笔记

1.require：java环境，本地可用的hadoop，远程可访问的mysql

2.拷贝hive文件（hive-2.2.1）

3.设置环境变量

export HIVE_HOME=/data/spark/bin/hive
export PATH=$PATH:$HIVE_HOME/bin

4.拷贝mysql以及java连接类

yum install -y mysql-server mysql-devel mysql-connector-java 
cp /usr/share/java/mysql-connector-java.jar $HIVE_HOME/lib/

5.初始化表结构

cd $HIVE_HOME/scripts/metastore/upgrade/mysql
mysql -h {host} -P {port} -u {user} -p{password} {db} < $HIVE_HOME/scripts/metastore/upgrade/mysql/hive-schema-2.1.0.mysql.sql

6.配置hive连接mysql

vi $HIVE_HOME/conf/hive-site.xml
<configuration>
<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql://{host}:{port}/{db}?createDatabaseIfNotExist=true</value>
<description>metadata is stored in a MySQL server</description>
</property>
<property>
<name>javax.jdo.option.ConnectionDriverName</name>
<value>com.mysql.jdbc.Driver</value>
<description>MySQL JDBC driver class</description>
</property>
<property>
<name>javax.jdo.option.ConnectionUserName</name>
<value>{user}</value>
<description>user name for connecting to mysql server</description>
</property>
<property>
<name>javax.jdo.option.ConnectionPassword</name>
<value>{password}</value>
<description>password for connecting to mysql server</description>
</property>
</configuration>

7.测试

hive
hive> create table saurzcode(id int, name string);

8.校验

mysql> select * from TBLS;
