Chapter 5. Resolved issues

This section describes notable issues that have been resolved in Red Hat OpenShift Data Science 2.4.

DATA-SCIENCE-PIPELINES-OPERATOR-294 - Scheduled pipeline run that uses data-passing might fail to pass data between steps, or fail the step entirely

A scheduled pipeline run that uses an S3 object store to store the pipeline artifacts might fail with an error such as the following:

Bad value for --endpoint-url "cp": scheme is missing. Must be of the form http://<hostname>/ or https://<hostname>/

This issue occurred because the S3 object store endpoint was not successfully passed to the pods for the scheduled pipeline run. This issue is now resolved.

RHODS-4769 - GPUs on nodes with unsupported taints cannot be allocated to notebook servers

GPUs on nodes marked with any taint other than the supported nvidia.com/gpu taint could not be selected when creating a notebook server. This issue is now resolved.

RHODS-6346 - Unclear error message displays when using invalid characters to create a data science project

When creating a data science project’s data connection, workbench, or storage connection using invalid special characters, the following error message was displayed:

the object provided is unrecognized (must be of type Secret): couldn't get version/kind; json parse error: unexpected end of JSON input ({"apiVersion":"v1","kind":"Sec ...)

The error message failed to clearly indicate the problem. The error message now indicates that invalid characters were entered.

RHODS-6950 - Unable to scale down workbench GPUs when all GPUs in the cluster are being used

In earlier releases, it was not possible to scale down workbench GPUs if all GPUs in the cluster were being used. This issue applied to GPUs being used by one workbench, and GPUs being used by multiple workbenches. You can now scale down the GPUs by selecting None from the Accelerators list.

RHODS-8939 - Default shared memory for a Jupyter notebook created in a previous release causes a runtime error

Starting with release 1.31, this issue is resolved, and the shared memory for any new notebook is set to the size of the node.

For a Jupyter notebook created in a release earlier than 1.31, the default shared memory for a Jupyter notebook is set to 64 MB and you cannot change this default value in the notebook configuration.

To fix this issue, you must recreate the notebook or follow the process described in the Knowledgebase article How to change the shared memory for a Jupyter notebook in Red Hat OpenShift Data Science.

RHODS-9030 - Uninstall process for OpenShift Data Science might become stuck when removing kfdefs resources

The steps for uninstalling OpenShift Data Science self-managed are described in Uninstalling Red Hat OpenShift Data Science self-managed.

However, even when you followed this guide, you might have seen that the uninstall process did not finish successfully. Instead, the process stayed on the step of deleting kfdefs resources that were used by the Kubeflow Operator. As shown in the following example, kfdefs resources might exist in the redhat-ods-applications, redhat-ods-monitoring, and rhods-notebooks namespaces:

$ oc get kfdefs.kfdef.apps.kubeflow.org -A

NAMESPACE                  NAME                                   AGE
redhat-ods-applications    rhods-anaconda                         3h6m
redhat-ods-applications    rhods-dashboard                        3h6m
redhat-ods-applications    rhods-data-science-pipelines-operator  3h6m
redhat-ods-applications    rhods-model-mesh                       3h6m
redhat-ods-applications    rhods-nbc                              3h6m
redhat-ods-applications    rhods-osd-config                       3h6m
redhat-ods-monitoring      modelmesh-monitoring                   3h6m
redhat-ods-monitoring      monitoring                             3h6m
rhods-notebooks            rhods-notebooks                        3h6m
rhods-notebooks            rhods-osd-config                       3h5m

Failed removal of the kfdefs resources might have also prevented later installation of a newer version of OpenShift Data Science. This issue no longer occurs in Red Hat OpenShift Data Science 2.4.

RHODS-9764 - Data connection details get reset when editing a workbench

When you edited a workbench that had an existing data connection and then selected the Create new data connection option, the edit page might revert to the Use existing data connection option before you had finished specifying the new connection details. This issue is now resolved.
