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?</P> Tue, 30 Dec 2025 11:57:42 GMT HuseynNajafli 2025-12-30T11:57:42Z https://community.dynatrace.com/t5/Open-Q-A/Issue-with-Simba-Spark-ODBC-Driver-and-Spark-SQL-Queries-after/m-p/292284#M38352 <P>Hello</P><P>We are connecting to a Spark SQL database via the Simba Spark ODBC driver.

I for sure recommend creating a support ticket with Dynatrace to let them investigate this issue.<BR /><BR />Besides this, you can do multiple remediating tasks right now.<BR /><BR /></P><P>1. Lower the monitoring mode to Infrastructure, which disabled dynatrace injection at all and therefore disable code-level injection.&nbsp;<BR />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.<BR /><BR /></P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="michiel_otten_0-1767096566903.png" style="width: 400px;"><img src="https://community.dynatrace.com/t5/image/serverpage/image-id/31369i3F93A9BAA479AAFE/image-size/medium?v=v2&amp;px=400" role="button" title="michiel_otten_0-1767096566903.png" alt="michiel_otten_0-1767096566903.png" /></span></P><P>&nbsp;</P><P><BR /><BR /><BR /><BR /></P> Tue, 30 Dec 2025 12:13:19 GMT https://community.dynatrace.com/t5/Open-Q-A/Issue-with-Simba-Spark-ODBC-Driver-and-Spark-SQL-Queries-after/m-p/292287#M38353 michiel_otten 2025-12-30T12:13:19Z
