Unable to open/execute Knime workflow with Spark Linear/Logistic Regression node. Facing below issue.
"Workflow could not be loaded. breeze/linalg/Vector"
"Workflow could not be loaded. breeze/generic/UFunc$UImpl2"
I am able to execute only Spark Random Forest Learner, Spark Decision Tree MLIB nodes, for all other Spark MLIB nodes I am encountering above error. I am facing this issue after I did an update.
Please let me know how to resolve this issue.
this seems to be a problem with the installation. To reinstall the KNIME Spark Executor please perform the following steps:
- Open KNIME
- Go to Help->Installation Details
- In the Installed Software tab select the KNIME Spark Executor and click on the Uninstall button
- Close KNIME
- Add -clean in the next line below the -startup option to the knime.ini file in your KNIME installation directory
- Start KNIME and install the KNIME Spark Executor again via File->Install KNIME Extensions
Sorry for the inconveniences.
