Known Issues and Limitations

This section lists the known issues and limitations specific to Cloudera Data Science Workbench.


  • AMPs display warning message even though engine:15 is present. For AMPs, the UI might show warning message even though engine:14 or engine:15 is present as the supported engine for the AMP. You can disregard this message if either of these engines are selected.

    Cloudera Bug: DSE-19086

  • AMP creation step might be reported as succeeded, even if a requirement installation failed. Such installation steps might fail due to intermittent network issues.

    Workaround: Check and rerun related project creation steps.

    Cloudera Bug: DSE-17966

  • Certain AMPs might not provide default ML Runtimes on the project configuration page. In such cases Cloudera recommends using Python 3.7 as a kernel. Later python kernels might not be supported due to the libraries used (for example, torch 1.6.0 does not support python 3.9).

API v2

  • Limitation: search_filter is not being applied on Apiv2/python calls.

    Cloudera Bug: DSE-18804

  • API v2 Limitation: Custom project templates created by an Administrator are not supported by API v2.

    Cloudera Bug: DSE-18758

  • API v2 Limitation: Jobs configured via API v2 can only be set to send email notifications on success events.

    Cloudera Bug: DSE-18754

  • API v2 known issue: Job creation with invalid fields can cause the created client to fail running further and provide 502 responses going forward.

    Workaround: Stop the code execution and recreate the client.

    Cloudera Bug: DSE-18753

  • API v2 limitation: Using API v2 workloads can be created to use Python2 kernels, even though site administration has disabled python2 support on the UI.

    Cloudera Bug: DSE-18744

  • API v2 swagger: Authorization header is not passed to some endpoint calls

    Cloudera Bug: DSE-18703

  • Projects deleted by APIv2 are not automatically garbage collected.

    Workaround: Mark every old deleted project for garbage collection.

    Cloudera Bug: DSE-21888


  • External emails mentioned in Job settings, vanish every time the job is paused and resumed.

    Cloudera Bug: DSE-18987

  • Environment Variables values are only visible in sessions, applications, jobs, and models that you launched. You can use these environment variables to securely store confidential information such as your AWS or database credentials.

    Cloudera Bug: DSE-19066

  • MLops Governance is not working - Atlas/Kafka/CDSW configuration issue.

    Cloudera Bug: DSE-18892

  • Workers which cannot be scheduled because of pod quota limit seem to be hang around and consuming resources.

    Cloudera Bug: DSE-18479


  • During build time, the model/experiment does not have access to user level environment variables.

    Workaround: Add user level environment variables on the Administrative/Project level instead.

    Cloudera Bug: DSE-19067

  • Model creation fails with ambiguous "Failed to create model" message when there is already a model with the same name. Issue also applies when using APIv2 directly.

    Cloudera Bug: DSE-7509

  • When viewing projects, if you select a team context you'll still only see your own projects.
