vi hive-site.xml <?xml version="1.0" encoding="UTF-8" standalone="no"?> <?xml-stylesheet type="text/xsl" href="configuration.xsl"?> <configuration> <property> <name>javax.jdo.option.ConnectionURL</name> <value>jdbc:mysql://zhaosai:3306/hive?useSSL=false</value> </property> <property> <name>javax.jdo.option.ConnectionDriverName</name> <value>com.mysql.cj.jdbc.Driver</value> </property> <property> <name>javax.jdo.option.ConnectionUserName</name> <value>root</value> </property> <property> <name>javax.jdo.option.ConnectionPassword</name> <value>jqe6b6</value> </property> <property> <name>hive.metastore.schema.verification</name> <value>false</value> </property> </configuration>

这是一个 Hive 的配置文件，其中配置了 Hive 与 MySQL 数据库的连接信息，包括连接 URL、驱动名称、用户名和密码。此外，还有一个配置项 hive.metastore.schema.verification，设置为 false，表示关闭元数据存储的 schema 验证。这个文件的路径是 vi hive-site.xml。需要注意的是，这个配置文件的具体内容可能因环境不同而有所变化。

怎么新建hive-site.xml

你可以通过以下步骤新建hive-site.xml：

1. 打开文本编辑器，如Notepad++或Sublime Text等。
2. 创建一个新文件并将其命名为hive-site.xml。
3. 将以下代码复制并粘贴到文件中：

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql://localhost/metastore?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>hiveuser</value>
<description>username to use against metastore database</description>
</property>
<property>
<name>javax.jdo.option.ConnectionPassword</name>
<value>hivepassword</value>
<description>password to use against metastore database</description>
</property>
</configuration>

4. 保存文件并将其放置在Hive的配置目录中，通常是$HIVE_HOME/conf/。

注意：以上代码是一个示例，你需要根据你的具体情况修改其中的参数。

hive-Metastore-site.xml

The hive-metastore-site.xml is a configuration file used by the Hive Metastore service in Apache Hive. The Metastore is a central repository that stores metadata information about Hive tables, partitions, and databases.

The hive-metastore-site.xml file contains configuration properties that define how the Hive Metastore service runs. These properties include the database and table configurations, the location of the Hive Metastore service, the type of database used to store the metadata, and security settings.

Here is an example of a hive-metastore-site.xml file:

<?xml version="1.0"?>
<configuration>
  <property>
    <name>javax.jdo.option.ConnectionURL</name>
    <value>jdbc:mysql://localhost/metastore_db?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>hiveuser</value>
    <description>username to use against metastore database</description>
  </property>
  <property>
    <name>javax.jdo.option.ConnectionPassword</name>
    <value>password</value>
    <description>password to use against metastore database</description>
  </property>
</configuration>

This configuration file specifies that the Hive Metastore service will use a MySQL database to store its metadata. It also defines the connection settings for the database, including the URL, driver name, username, and password.

Overall, the hive-metastore-site.xml file is an important configuration file for managing the Hive Metastore service, and it should be configured carefully to ensure the proper functioning of the Hive service.
