This release (2.5.0-h2-b1) of Cloudera DataFlow (CDF) on CDP Public Cloud resolves an issue with NiFi cluster autoscaling behavior that can cause unnecessary flow disruptions.

Fixed issues

  • CDPDFX-7567 - Fixed unnecessary NiFi cluster pod restarts triggered by autoscaling operations.

    • This issue impacted only those running DataFlow 2.5.0-h2-b1 and deployments configured with autoscaling enabled.

    • Any scale-up or scale-down operation would trigger unnecessary restarts of existing pods resulting in temporary flow disruptions.

    • Upgrading to this new DataFlow version automatically resolves the issue.
