Issue with Simba Spark ODBC Driver and Spark SQL Queries after Dynatrace Injection

[HuseynNajafli]

Hello

We are connecting to a Spark SQL database via the Simba Spark ODBC driver. When OneAgent is disabled, no issues occur. However, once OneAgent is injected, some queries return a 200 response, while others encounter errors such as SSL issues and "no more data to read." How can we resolve this problem?

Hi there,

Looking at your issue I think you've installed the DYnatrace OneAgent in Full Stack mode and code-injection is causing the issues. I for sure recommend creating a support ticket with Dynatrace to let them investigate this issue.

Besides this, you can do multiple remediating tasks right now.

1. Lower the monitoring mode to Infrastructure, which disabled dynatrace injection at all and therefore disable code-level injection. 
2. If you don't want this, investigatre which process is doing the ODBC calls. YOu can also disable deep monitoring here at all or disable the injection of 1 of the technologies (f.e. Java or .NET) used by that process.
