Trino is an open-source distributed SQL query engine designed for running interactive analytic queries against data sources of all sizes. It is particularly useful for querying large datasets across multiple data sources, including Hadoop, relational databases, and object storage systems. Trino allows users to perform complex queries with high performance and scalability.
When using Trino, you might encounter an error message stating UNSUPPORTED_OPERATION_MODE. This error indicates that the operation mode you are attempting to use is not supported by Trino. This can halt your query execution and prevent you from accessing the data you need.
This error often arises when trying to execute a query or operation that requires a specific mode not available in your current Trino setup. It can also occur if there is a mismatch between the operation mode and the Trino version you are using.
The UNSUPPORTED_OPERATION_MODE error is a clear indication that the operation mode specified in your query or configuration is not recognized by Trino. This could be due to using an outdated version of Trino or attempting to use a feature that is not yet implemented in the version you are running.
Ensure that the operation mode you are trying to use is compatible with your version of Trino. You can check the Trino release notes for information on supported features and modes.
To resolve the UNSUPPORTED_OPERATION_MODE error, follow these steps:
First, confirm the version of Trino you are using. You can do this by running the following command in your Trino CLI:
SELECT version();
Compare your version with the latest release notes to ensure compatibility with the operation mode you intend to use.
If your version supports the desired operation mode, check your Trino configuration files to ensure they are correctly set up. Configuration files are typically located in the etc directory of your Trino installation. Look for any settings related to operation modes and adjust them as necessary.
If your current version does not support the required operation mode, consider upgrading to a newer version of Trino. Follow the official installation guide to upgrade your Trino setup.
By ensuring that your Trino version and configuration are aligned with the supported operation modes, you can effectively resolve the UNSUPPORTED_OPERATION_MODE error. Keeping your Trino installation up-to-date and consulting the official documentation will help you avoid similar issues in the future.
