啓動hive時 mysql報錯

異常

1.啓動hive時  mysql報錯

java.sql.SQLException: Access denied for user 'hadoop'@'master' (using password: YES)

問題：配置文件出錯 或者用戶授權有問題。

解決方式：

對用戶重新授權  確保主機名和用戶名是當前虛擬機相對應

重寫配置文件

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
    <property>
        <name>hive.metastore.local</name>
        <value>true</value>
    </property>
    <property>
        <name>javax.jdo.option.ConnectionURL</name>
         <value>jdbc:mysql://master:3306/hive_13?characterEncoding=UTF-8</value>
    </property>
    <property>
        <name>javax.jdo.option.ConnectionDriverName</name>
        <value>com.mysql.jdbc.Driver</value>
    </property>
    <property>
        <name>javax.jdo.option.ConnectionUserName</name>
        <value>hadoop</value>
    </property>
    <property>
        <name>javax.jdo.option.ConnectionPassword</name>
        <value>hadoop</value>
    </property>

</configuration>

創建mysql用戶：

grant  all on *.    * to hadoop@'%'  identified 'hadoop';

回收用戶：

revok all on *.   *  from  hadoop@'%' identetified 'hadoop';
