Known issues

These are the known problems as of DSS 4.1.2


  • Window recipe: in DSS engine, lag computation is wrong when overriding the name of the lag column.

Machine learning

  • Scoring using a deployed ensemble fails until said ensemble has been retrained
  • Ensembling ensembles is not supported when multi-user-security is enabled
  • The evaluation recipe outputs invalid metric values (F1, Recall, Precision) for binary classification


  • Writing datasets from R notebooks fails when DSS is in multi-user-security mode
  • Multi-user-security mode: Hive recipe validation fails if UNIX user is not the same as Hadoop user. Please contact Dataiku support for workarounds
