FAILED: HiveException org.apache.hadoop.hive.ql.metadata.HiveException: MetaException(message:Hive metastore database is not initialized. Please use schematool (e.g. ./schematool -initSchema -dbType ...) to create the schema. If needed, don't forget to include the option to auto-create the underlying database in your JDBC connection string (e.g. ?createDatabaseIfNotExist=true for mysql))

这个错误是因为你没有初始化Hive Metastore数据库。你需要使用schematool命令来初始化它。你可以尝试运行下面的命令来初始化它：

schematool -initSchema -dbType <your_db_type> -verbose

请将`<your_db_type>`替换为你所使用的数据库类型，例如mysql、derby等。

如果你想自动创建底层数据库，可以在JDBC连接字符串中添加`?createDatabaseIfNotExist=true`选项。例如，如果你使用的是mysql数据库，你可以使用以下命令连接到Hive Metastore：

jdbc:mysql://<host_name>:<port>/<database_name>?createDatabaseIfNotExist=true

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

This error message indicates that Hive was unable to create an instance of the SessionHiveMetaStoreClient class, which is responsible for managing metadata related to Hive tables and databases.

There could be several reasons for this error, including:

1. Missing or incorrect configuration: Check that the Hive configuration files are correctly set up and that the required properties are specified.

2. Incompatible versions: Make sure that the version of Hive you are using is compatible with the version of Hadoop and other related components.

3. Permissions issues: Ensure that the user running Hive has the necessary permissions to access and modify the metadata store.

4. Network issues: Check that the network connectivity between the Hive server and the metadata store is working correctly.

To resolve this error, you may need to investigate further to determine the root cause of the issue. Check the Hive logs and any related error messages to get more information on the exact nature of the problem.
