Original GitHub issue: https://github.com/dbeaver/cloudbeaver/issues/3934

Yes. I need to connect to Apache Impala (Cloudera Impala) clusters through CloudBeaver Community Edition for data analysis and querying. Currently, there is no native Impala driver available in CloudBeaver CE.

Describe the solution you'd like

Add native support for Apache Impala JDBC driver in CloudBeaver Community Edition, similar to the existing support for Kyuubi, Trino, and other big data databases.

Driver Details:

Driver Name: Cloudera Impala JDBC Driver
Driver Class: com.cloudera.impala.jdbc.Driver
URL Pattern: jdbc:impala://{host}:{port}/{database}
Default Port: 21050
Download Source: Cloudera/Apache Impala official repositories

Describe alternatives you've considered

Currently using Apache Kyuubi driver as a workaround since it uses a similar Thrift protocol. However, native Impala support would provide:

Better compatibility
Full feature support
Proper error handling
Optimized performance

Additional context

Impala is widely used for big data analytics
DBeaver Desktop already supports Impala natively
This would complement CloudBeaver's existing big data database support (Hive, Spark, Kyuubi)
This feature would benefit the open-source community

Would greatly appreciate if this could be considered for a future release. Thank you!

Hello @salomaolopes !

Thank you for your request and for the detailed explanation! 🦫

CloudBeaver Community Edition does not include the Impala JDBC driver out-of-the-box. However, you can add it manually using the built-in driver management. Here is the documentation describing how to add a custom JDBC driver:
https://github.com/dbeaver/cloudbeaver/wiki/Adding-new-database-drivers

Currently, we avoid bundling additional JDBC drivers into the default CE image, as this noticeably increases the image size and affects startup time and updates for all users. Because of that, we only include the most commonly used drivers by default, and all others can be added manually when needed.

We understand the importance of Impala support and appreciate you sharing your use case. We’ll keep this request in mind when planning future improvements.

Thanks again for your feedback! 💙

Hello @dariamarutkina!

Thank you so much for the quick response and for pointing me to the documentation! 🙏

I really appreciate you keeping this request in mind for future improvements. I completely understand the reasoning behind not bundling all drivers by default to keep the image size manageable.

I will follow the documentation you provided to add the Impala driver manually.

Thanks again for your help.

@dariamarutkina @salomaolopes Could you please help me figure out why I still can't see the cloud_impala option on the interface despite the above configurations?

I think there’s an issue with this document—it fails to mention that CloudBeaver automatically downloads DBeaver’s source code and packages dependencies on them. I’ve been confused about why the document instructs modifying DBeaver’s source code files.

I test the driver of oceanbase and netezza , it is work well, but why only cloudera_impala can't be success. Is the categories="hadoop" can not be supported?
