Hi everyone,

I've been stuck for the past two days on this issue with my Databricks JDBC driver and I'm hoping someone can give me more insight into how to troubleshoot. I am using the Databricks JDBC driver in RStudio and the connection was working fine until two days ago. There was a companywide Windows update and now cloud fetch is failing and I get the following error message:

Error in .jcall(rp, "I", "fetch", stride, block) :

java.sql.SQLException: [Simba][SparkJDBCDriver](500638) The file <blob URL> has not been downloaded successfully and the driver will not retry due to exceeding of the max retry limit 10, you can increase the max retry limit by setting MaxConsecutiveResultFileDownloadRetries.

The driver however is still working with small datasets <1MB. Has anyone ever encountered this issue and how would I fix it? Thank you in advance for your help.

Kind Regards,

Debbie

@Debbie Ng can you try to download 2.6.32 and test please

@karthik p Where is v2.6.32 available? The Databricks JDBC Driver page only has v2.6.29 as the latest driver. Thank you for your help!

@karthik p No, unfortunately the same issue still occurs with the updated version.

@Debbie Ng From your message I see there was a windows update and this failure started. based on the conversation you tried latest version of the driver and still you face the problem. I believe this is something related to the Java version compatibility with the latest update.
