unable to load the dataframe from cosmos

Shubham Mehta 51 Reputation points Microsoft Employee


I am trying to load the dataframe from cosmos and unable to do that. I am trying the following command:

   def load_dataframe(self, query):      
       return self.spark_session.read.format('com.microsoft.azure.cosmosdb.spark').options(**self._make_connection(query)).load()  

And I am seeing the below error:

I have tried the following steps as well:

   You need to build the repository into the jar file first using SBT. Then include it to your spark cluster.  
   I know there will be a lot of people having trouble with buiding this jar file (include myself of several hours ago), so I will guide you how to build the jar file, step by step:  
   Go to https://www.scala-sbt.org/download.html to download SBT, then install it.  
   Go to https://github.com/Azure/azure-cosmosdb-spark and download the zip file.  
   Open the folder of the repository you have just downloaded, right click in the blank space and click "Open PowerShell windows here" . https://i.stack.imgur.com/Fq7NX.png  
   In the Shell windows, type "sbt" then press enter. It may require you to download the Java Development Kit. If so, go to https://www.oracle.com/java/technologies/javase-downloads.html to download and install it. You may need to close and reopen the shell windows after installing.  
   If things go right, you may see this screen: https://i.stack.imgur.com/fMxVr.png  
   After the above step has done its job, type "package". The shell may show you something like this, and it may take you a long time to finish the job. https://i.stack.imgur.com/hr2hw.png  
   After the build is done, go to the "target" folder, then "scala-2.12" folder to get the jar file. https://i.stack.imgur.com/Aziqy.png  
   After you got the jar file, include it to the Spark cluster.  


Can anybody help me with this problem? Or what can I do to fix this.

    Hello @Shubham Mehta ,

    Thanks for the question and using MS Q&A platform.

    I would suggest you to use the below connector to read the Cosmos data into Dataframe:


    For more details, refer to Azure Cosmos DB Apache Spark 3 OLTP Connector for Core (SQL) API: Release notes and resources.

    Hope this will help. Please let us know if any further queries.
