Ubuntu系统下安装并配置hive-2.1.0

说在前面的话

　　默认情况下，Hive元数据保存在内嵌的Derby数据库中，只能允许一个会话连接，只适合简单的测试。实际生产环境中不使用，为了支持多用户会话，

则需要一个独立的元数据库，使用MySQL作为元数据库，Hive内部对MySQL提供了很好的支持。

在Ubuntu系统下安装并配置hive详细正确步骤如下！

一、mysql-server和mysql-client的下载

root@SparkSingleNode:/usr/local# sudo apt-get install mysql-server mysql-client （Ubuntu版本）

　　我这里，root密码，为rootroot。

二、启动MySQL服务

root@SparkSingleNode:/usr/local# sudo /etc/init.d/mysql start 　　　　　（Ubuntu版本）　　　　　
* Starting MySQL database server mysqld [ OK ]
root@SparkSingleNode:/usr/local#

附加说明，

sudo /etc/init.d/mysql restart 这是重启

sudo /etc/init.d/mysql stop 这是停止

三、进入mysql服务

Ubuntu里的mysql里有个好处，直接自己对root@下的所有，自己默认设置好了

root@SparkSingleNode:/usr/local# mysql -uroot -p
Enter password:　　 //输入rootroot
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 43
Server version: 5.5.53-0ubuntu0.14.04.1 (Ubuntu)

Oracle is a registered trademark of Oracle Corporation and/or its
affiliates. Other names may be trademarks of their respective
owners.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql> CREATE USER 'hive'@'%' IDENTIFIED BY 'hive';

mysql> GRANT ALL PRIVILEGES ON *.* TO 'hive'@'%' WITH GRANT OPTION;

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

mysql> exit;
Bye
root@SparkSingleNode:/usr/local#

在ubuntu系统里，默认情况下MySQL只允许本地登录，所以需要修改配置文件将地址绑定注释。

sudo gedit /etc/mysql/my.cnf

找到 # bind-address = 127.0.0.1 注释掉这一行就可以啦

重启mysql服务

sudo service mysqld restart

然后，建立Hive专用的元数据库，记得用我们刚创建的"hive"账号登录。

mysql -u hive -p hive

CREATE DATABASE hive_metadata

四、安装hive

　　这里，很简单，不多赘述。

spark@SparkSingleNode:/usr/local/hive$ ll
total 12
drwxr-xr-x 3 spark spark 4096 11月 21 10:39 ./
drwxr-xr-x 15 root root 4096 11月 21 10:25 ../
drwxrwxr-x 9 spark spark 4096 11月 21 10:38 apache-hive-2.1.0-bin/
spark@SparkSingleNode:/usr/local/hive$ mv apache-hive-2.1.0-bin hive-2.1.0
spark@SparkSingleNode:/usr/local/hive$ ls
hive-2.1.0
spark@SparkSingleNode:/usr/local/hive$ cd hive-2.1.0/
spark@SparkSingleNode:/usr/local/hive/hive-2.1.0$ ls
bin examples jdbc LICENSE README.txt scripts
conf hcatalog lib NOTICE RELEASE_NOTES.txt
spark@SparkSingleNode:/usr/local/hive/hive-2.1.0$ cd conf/
spark@SparkSingleNode:/usr/local/hive/hive-2.1.0/conf$ ls
beeline-log4j2.properties.template ivysettings.xml
hive-default.xml.template llap-cli-log4j2.properties.template
hive-env.sh.template llap-daemon-log4j2.properties.template
hive-exec-log4j2.properties.template parquet-logging.properties
hive-log4j2.properties.template
spark@SparkSingleNode:/usr/local/hive/hive-2.1.0/conf$ cp hive-default.xml.template hive-site.xml
spark@SparkSingleNode:/usr/local/hive/hive-2.1.0/conf$

五、配置hive

<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql://192.168.80.128:3306/hive_metadata?createDatabaseIfNotExist=true</value>
<description>
JDBC connect string for a JDBC metastore.
To use SSL to encrypt/authenticate the connection, provide database-specific SSL flag in the connection URL.
For example, jdbc:postgresql://myhost/db?ssl=true for postgres database.
</description>

<property>
<name>javax.jdo.option.ConnectionDriverName</name>
<value>com.mysql.jdbc.Driver</value>
<description>Driver class name for a JDBC metastore</description>
</property>

<property>
<name>javax.jdo.option.ConnectionUserName</name>
<value>hive</value>
<description>Username to use against metastore database</description>
</property>

<property>
<name>javax.jdo.option.ConnectionPassword</name>
<value>hive</value>
<description>password to use against metastore database</description>
</property>

spark@SparkSingleNode:/usr/local/hive/hive-2.1.0/conf$ cp hive-env.sh.template hive-env.sh
spark@SparkSingleNode:/usr/local/hive/hive-2.1.0/conf$ vim hive-env.sh

spark@SparkSingleNode:/usr/local/hive/hive-2.1.0/bin$ vim hive-config.sh

export JAVA_HOME=/usr/local/jdk/jdk1.8.0_60
export HIVE_HOME=/usr/local/hive/hive-2.1.0
export HADOOP_HOME=/usr/local/hadoop/hadoop-2.6.0

vim /etc/profile

#hive
export HIVE_HOME=/usr/local/hive/hive-2.1.0
export PATH=$PATH:$HIVE_HOME/bin

source /etc/profile

将mysql-connector-java-***.jar，复制到hive安装目录下的lib下。

spark@SparkSingleNode:/usr/local/hadoop/hadoop-2.6.0$ sbin/start-all.sh

　　一般，上面，就可以足够安装正确了！

附赠问题

mysql-connector-java-5.1.21-bin.jar换成较高版本的驱动如mysql-connector-java-6.0.3-bin.jar

　　试过了，不是这个问题。
