How to connect Denodo with HDFS?

Hi. Does anyone know what is the best way to connect Denodo with HDFS? I cannot find any article or how-to about this topic. I added data sources like Oracle and MySQL databases, Hive. But I need to connect to HDFS.

Hello! There are no inbuilt connection support for HDFS, but, Denodo is highly flexible. I would create a custom wrapper in Denodo Virtual DataPort to consume the files hosted on HDFS, you can read more about custom wrappers on [Developing Custom Wrappers](https://community.denodo.com/docs/html/browse/7.0/vdp/developer/developing_extensions/developing_custom_wrappers/developing_custom_wrappers ). On the other hand, if you are a valid support user, then you could download the “Denodo Distributed File System Custom Wrapper” from the Denodo Support Site under “Downloads > Denodo Connects” option. The wrapper distribution comes with detailed manual on the usage. Hope this helps!

Hi team, I suppose this wrapper "Denodo Distributed File System Custom Wrapper" needs to be downloaded in server side, and do some configuration on client side. Do we have some manul about how to configure it in client when create a data source in VDP? Thanks.

Hi, Generally, Denodo Distributed File System Custom Wrapper allows access for Delimited files and Non-Standard files stored in HDFS and AWS S3 such as Avro, Map files, Sequence files, Parquet files. Further, it contains a custom wrapper to retrieve file listing information from the distributed file system and display it in a relational way. If you are a valid support user, then, you could download this custom wrapper from Downloads > [Denodo Connects](https://support.denodo.com/resources/denodo-connect/list/Denodo%208.0) section of the Support Site. For more information, you could refer to the [Denodo Distributed File System Custom Wrapper - User Manual](https://community.denodo.com/docs/html/document/denodoconnects/8.0/en/Denodo%20Distributed%20File%20System%20Custom%20Wrapper%20-%20User%20Manual). Hope this helps!
