Cloudera CDP with Impalad 3.4.0 jdbc connector

We are currently using Denodo 7 (future plans to upgrade to 8) and are currently using the Impala 2.3 jdbc connector with Cloudera CDH 6.3. We will be upgrading our current Cloudera environment to Cloudera CDP 7.1.6 with Impala 3.4.0 and was curious if Denodo has performed any testing with the new Impala jdbc drivers for CDP. Is there any recommendation on which jdbc driver we should use for this upgrade? Or will the existing Impala 2.3 jdbc driver work as is?

Hi, Denodo Platform 7.0 and 8.0 supports Impala 2.3 JDBC driver for connecting to Cloudera Impala Environment. The latest Impala driver is not yet officially tested with CDP 7 but you can connect to a higher version of driver and choose the latest Database adapter from Virtual DataPort. Latest driver can be downloaded from the vendor website and the driver should be imported in Virtual Dataport Administration Tool by following the steps mentioned in [Importing a JDBC Driver](https://community.denodo.com/docs/html/browse/8.0/en/vdp/administration/importing_extensions/importing_extensions#importing-a-jdbc-driver) documentation. Have a look at the [Connecting to Cloudera Impala from Denodo Platform](https://community.denodo.com/kb/en/view/document/How%20to%20connect%20to%20Cloudera%20Impala%20from%20the%20Denodo%20Platform) document for connection based information and the [JDBC data sources](https://community.denodo.com/docs/html/browse/8.0/en/vdp/administration/appendix/supported_jdbc_data_sources/supported_jdbc_data_sources) document to know about the support data sources and its versions. Besides, if you overcome any issues in future then if you are a valid support user you can open a support case and, our support team would help you with it. Hope this helps!
