CDS Workbench with Spark Versions Below 2.0

mdnickens — Tue, 21 Apr 2026 13:28:27 GMT

Hello,

Does CDS Workbench work alongside versions of Spark below 2.0? We're running 1.6.0 and would like to add CDSW. We're upgrading to 2.2 eventually, but we'd like to test drive the workbench beforehand.

Thanks!

No, it requires Spark 2.

Cloudera Data Science Workbench only supports Spark 2.x, it doesn't support
the Spark 1.x line. Spark 2 has a number of important improvements for
data science workloads which is why we have focused on Spark 2 support
only. You can still use Spark 1.x on the same cluster, but only Spark 2
within CDSW.

Best,
Tristan
