hive安装常见错误

hive编译出错

mvn clean package -DskipTests -Phadoop-2 -Pdist

失败日志1

暂未解决。。。

有可能时网络的原因。

安装后启动不起来

日志：

Caused by: java.sql.SQLException: Unable to open a test connection to the given database. JDBC url = jdbc:mysql://hadoop000:3306/metastore?createDatabaseIfNotExist=true, username = root. Terminating connection pool (set lazyInit to true if you expect to start your database after your app). Original Exception: ------

网上查看后，总结了解决方法

1.查看hive-site.xml是否配置正确，mysql的账号密码不能写错。

2.hive没有初始化，进行初始化

schematool -dbType mysql -initSchema

3.hive版本过高。

4.HIVE_HOME/lib 下的derby-10.11.1.1.jar问题，，把derby-10.11.1.1.jar 换成derby-10.10.2.0.jar问题成功解决

综上，我的问题是hive-site.xml配置文件中mysql的密码写错了。

配置hive前必不可少的一项，给mysql赋予权限

mysql -uroot -p
 
>grant all privileges on *.* to root@"%" identified by "123456" with grant option;
>grant all privileges on *.* to root@"hadoop000" identified by "123456" with grant option;
>grant all privileges on *.* to root@"localhost" identified by "123456" with grant option;
>quit;
 
解释：

grant 权限1,权限2,…权限n on 数据库名称.表名称 to 用户名@用户地址 identified by ‘连接口令’;）

* mysql数据库默认只允许root用户通过localhost/127.0.0.1来登录使用

* 上面带有grant的那条语句中：

all：表示所有权限；

*.*：表示数据库.数据表；

root：表示授权给哪个用户，用户名可以任意指定，如果没有会自动创建；

'hadoop000' ：授权给哪台主机

'123456'：授权给用户来登录的密码

如果不确定有没有成功，可以查看 mysql.user

mysql >select host,user,password from mysql.user;
