HiveException java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient

This error message suggests that there is an issue with the Hive metadata store client. The metadata store client is responsible for managing the metadata of tables and other objects in Hive. There are several reasons why this error might occur, including:

1. Incorrect configuration: The configuration settings for the metadata store client might be incorrect. Check the configuration files to ensure that the settings are correct.

2. Missing dependencies: The metadata store client might be missing some required dependencies. Check the classpath to ensure that all required JAR files are included.

3. Database connection issues: The metadata store client might be unable to connect to the underlying database. Verify that the database is running and that the connection settings are correct.

To resolve this issue, you can try the following steps:

1. Check the configuration files for any errors and ensure that the settings are correct.

2. Verify that all required JAR files are included in the classpath.

3. Verify that the database is running and that the connection settings are correct.

4. Restart the Hive service and try again.

If none of these steps resolve the issue, you may need to seek further assistance from the Hive community or support team.
