hive 必须安装mysql吗

Posted 2023-05-13

参考技术A 这个不是必须的，hive也有本地模式 参考技术B 先启 metasotre 再启hive server
hive --service metastore-----------Startup Hive Embedded
hive --service hiveserver-----------Startup Hive Standalone

hive安装与mysql对接

Hive只在一个节点上安装即可

必须有hadoop的支持

1.上传tar包
2.解压
tar -zxvf hive-0.9.0.tar.gz
3.配置mysql metastore（切换到root用户）
配置HIVE_HOME环境变量
rpm -qa | grep mysql
rpm -e mysql-libs-5.1.66-2.el6_3.i686 --nodeps
rpm -ivh MySQL-server-5.1.73-1.glibc23.i386.rpm 
rpm -ivh MySQL-client-5.1.73-1.glibc23.i386.rpm 
修改mysql的密码
/usr/bin/mysql_secure_installation
（注意：删除匿名用户，允许用户远程连接）
登陆mysql
mysql -u root -p


4.配置hive
cp hive-default.xml.template hive-site.xml 
修改hive-site.xml（删除所有内容，只留一个<property></property>）
添加如下内容：
<property>
 <name>javax.jdo.option.ConnectionURL</name>
 <value>jdbc:mysql://master:3306/hive?createDatabaseIfNotExist=true</value>
 <description>JDBC connect string for a JDBC metastore</description>
</property>


<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>root</value>
 <description>username to use against metastore database</description>
</property>


<property>
 <name>javax.jdo.option.ConnectionPassword</name>
 <value>123456</value>
 <description>password to use against metastore database</description>
</property>

5.安装hive和mysq完成后，将mysql的连接jar包拷贝到$HIVE_HOME/lib目录下
如果出现没有权限的问题，在mysql授权(在安装mysql的机器上执行)
mysql -u root -p
#(执行下面的语句  *.*:所有库下的所有表   %：任何IP地址或主机都可以连接)
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123' WITH GRANT OPTION;

FLUSH PRIVILEGES;

6.出现的常见错误

    原因是hadoop目录下存在老版本jline：
    /hadoop-2.5.2/share/hadoop/yarn/lib：
    -rw-r--r-- 1 root root   87325 Mar 10 18:10 jline-0.9.94.jar
     
    解决方法是：
    将hive下的新版本jline的JAR包拷贝到hadoop下：
    cp /hive/apache-hive-1.1.0-bin/lib/jline-2.12.jar ./
     
    /hadoop-2.5.2/share/hadoop/yarn/lib：
    -rw-r--r-- 1 root root   87325 Mar 10 18:10 jline-0.9.94.jar.bak
    -rw-r--r-- 1 root root  213854 Mar 11 22:22 jline-2.12.jar
     
    hive cli启动成功：
    root@ubuntu:/hive# hive
