This error message suggests that Hive is unable to create a connection to the Hive Metastore, which is responsible for storing metadata about the Hive tables and databases. There are several reasons why this error can occur:
1. Incorrect configuration: Verify that the Hive Metastore is properly configured and that the Hive configuration files are correctly set up.
2. Connectivity issues: Check that the Hive Metastore server is running and that there are no network connectivity issues between the Hive client and the Metastore server.
3. Permission issues: Ensure that the user running the Hive client has the necessary permissions to access the Hive Metastore.
4. Version incompatibility: It is possible that the Hive client and Metastore are running different versions, which can cause compatibility issues. Verify that the versions of the client and server are compatible.
5. Memory issues: If the Hive Metastore server is running out of memory, it may not be able to instantiate new connections. Check the memory usage of the Metastore server and increase its memory allocation if necessary.
To resolve this issue, try the following:
1. Verify that the Hive Metastore is properly configured and that the Hive configuration files are correctly set up.
2. Check that the Hive Metastore server is running and that there are no network connectivity issues between the Hive client and the Metastore server.
3. Ensure that the user running the Hive client has the necessary permissions to access the Hive Metastore.
4. Verify that the client and server versions are compatible.
5. Check the memory usage of the Metastore server and increase its memory allocation if necessary.
