OLE DB or ODBC error DataSource.Error - Spark

Hi,

I get the following error when I try to import data using Spark data source in PowerBI desktop. The dataset has about 30 million rows and 70 columns. 

Failed to save modifications to the server. Error returned: 'OLE DB or ODBC error: [DataSource.Error] ERROR [08S01] [Microsoft][Hardy] (71) Failed to establish connection with unknown error..'.

Could someone please help me resolve this? 

Thanks!
