Error using Spark Simba driver

Hey guys, new user here, trying out Siren to see if it will work out for our organization.

I’m trying to use a JDBC connection to our spark cluster using the Simba 4.1 driver.

Here’s how far I get:

  1. The “Test Connection” fails with a “feature not supported by driver” error (i’ll include the error from the logs below); HOWEVER,
  2. When I go to create a virtual index, it is able to list all tables and fields. I can create the virtual index.
  3. After building the data model, it won’t pull any data, such as in the “discover” tab. It gives me the same “feature not supported by driver” error.

Here is the error from the siren-distribution.log file:

In the UI, I get this error message all the time:

Error: Request to Elasticsearch failed: {“error”:{“root_cause”:[{“type”:“p”,“reason”:“SQLFeatureNotSupportedException: (10220) Driver does not support this optional feature.”}],“type”:“p”,“reason”:“SQLFeatureNotSupportedException: (10220) Driver does not support this optional feature.”,“caused_by”:{“type”:“s_q_l_feature_not_supported_exception”,“reason”:"(10220) Driver does not support this optional feature."}},“status”:500}

Again, it is able to enumerate all tables and fields, so the connection IS working.

Hi Timothy,

Thanks for reaching out to us, can you please make sure you have all these .jar files present inside the jdbc-plugins directory:


For more details please check the siren docs.

In addition, copy your license file to the jdbc-drivers plugin directory.

You can use this site to download the .jar files.


​Hi Manu,

When I download the drivers using the link you provided, it only contains the SparkJDBC41.jar file. None of the other files you listed are included in the download. Is there a previous version of the Simba drivers that Siren supports?

I did make sure to copy the license file to the jdbc-drivers directory as well.


Hi Tim,

We are able to replicate the issue and found it as a bug , we are working on fixing it. We will be drop-in the JDBC Spark Simba driver support soon on official docs with the steps to configure it.


Awesome! Thanks Manu! Looking forward to being able to try it out. I am hoping this is going to work for us.

Do you know about how long it will take? I’d like to showcase Siren to folks in our organization, but we have certain deadlines for our project.

Hi Tim,

We are working on fixing onto it , will update you as soon as it is available.


Hi Tim,

We have fixed the issue with the latest federate version. It is available to download it from here.
