Привет, я новичок в Hadoop, я только что установил hive 2.3.7 и настроил хранилище метаданных с помощью mysql в соответствии с этим руководством https://www.guru99.com/hive-metastore-configuration-mysql.html и этот https://ravi-chamarthy.medium.com/apache-hive-configuration-with-mysql-metastore-3ecb9a0df3a1. Вот мой файл hdfs-site.xml
<configuration>
<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql://localhost/metastore?createDatabaseIfNotExist=true</value>
<description>metadata is stored in a MySQL server</description>
</property>
<property>
<name>javax.jdo.option.ConnectionDriverName</name>
<value>com.mysql.cj.jdbc.Driver</value>
<description>MySQL JDBC driver class</description>
</property>
<property>
<name>javax.jdo.option.ConnectionUserName</name>
<value>hiveuser</value>
<description>user name for connecting to mysql server</description>
</property>
<property>
<name>javax.jdo.option.ConnectionPassword</name>
<value>hivepassword</value>
<description>password for connecting to mysql server</description>
</property>
Когда я выполнил schematool -initSchema -dbType mysql, все в порядке. Он инициализирует схему куста 2.3.0. когда я запускал куст и выполнял команду show databases или любую другую, я получал эти ошибки
hive> show databases;
Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class is `com.mysql.cj.jdbc.Driver'. The driver is automatically registered via the SPI and manual loading of the driver class is
generally unnecessary.

Примечание. Я использовал mysql 8.0.22, mysql-connector-java.jar, mysql-connector-java-8.0.22.jar ubuntu 18.04, hadoop 3.1.4.
