A：检查hive相关的配置文件，文件是否完整、格式是否正确，将正确格式文件重新上传至大数据相关路径，具体参考Primeton DI安装指南。如hive-site.xml如下错误格式

<?xml version="1.0" encoding="utf-8"?><configuration>
    <property>
        <name>javax.jdo.option.ConnectionURL</name>
        <value>jdbc:mysql://master01-n21egh1:3306/metastore?useSSL=false</value>
        <descrilption>JDBC connect string for a JDBC metastore</descrilption>
    </property>
    <property>
        <name>javax.jdo.option.ConnectionDriverName</name>
        <value>com.mysql.jdbc.Driver</value>
        <description>Driver class name for a JDBC metastore</description>
    </property>

..........省略.........

    <property>
        <name>hive.service.metrics.file.frequency</name>
        <value>30000</value>
    </property>
</configuration>

正确格式如下：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <property>
        <name>javax.jdo.option.ConnectionURL</name>
        <value>jdbc:mysql://master01-n21egh1:3306/metastore?useSSL=false</value>
        <descrilption>JDBC connect string for a JDBC metastore</descrilption>
    </property>
    <property>
        <name>javax.jdo.option.ConnectionDriverName</name>
        <value>com.mysql.jdbc.Driver</value>
        <description>Driver class name for a JDBC metastore</description>
    </property>

..........省略.........

    <property>
        <name>hive.service.metrics.file.frequency</name>
        <value>30000</value>
    </property>
