on my computer at work I’m be able to select the job manager “test for streaming and distributed processing” but on my private computer I can’t. Both Installations are unter Windows 11 and the KNIME-Version on both Systems is 4.7.4.
If I export a Workflow from my computer at work that is using “test for streaming and distributed processsing” in even one node and import it on my private computer so far i got the following error message:
Can’t restore node execution job manager: Unknown job manager factory id “org.knime.testing.streaming.testexecutor.StreamingTestNodeExecutionJobManagerFactory” (job manager factory possibly not installed?)
Has anyone an idea how to solve the problem? Thank you very much.
Just cheking. Is the " KNIME Streaming Execution (Beta)" plugin install in your home computer ?
Maybe worthwhile to check it by dragging and dropping the icon from its web link at the hub:
If you get the above message when dragging & dropping then it is already installed. Otherwise, it should get installed.
Hope it helps.
thanks for your answer. Yes, I checked if “KNIME Streaming Execution (Beta)” plugin is already installed and yes it is on both systems. For sure: I don’t want to use “Simple Streaming” like it will be provided by the plugin “KNIME Streaming Execution (Beta)”. The job-manager I am looking for will be called: “test for streaming and distributed processing”.
Well, I don’t know the source and the way i used to go to reinstall the desired job-manager-engine. Maybe it is part of another extension or plugin as well. I hope, somebody other like me used or tested it and remember the source. I know it is a feature under construction, but I like very much.
… this is I want to use:
It will be useable in most nodes and if selected the node icon changed. It get an grey arrow from left to right and a red text “TEST” above the arrow.
I use the Table-Creator-Node just for example.
if there’s a Test then it might be part of Testing extension There are couple of extension for testing but my guess would be KNIME Testing Framework UI extension.
Maybe I can talk some mistakes, but knime have a option for streaming nodes following this steps:
With a workflow openned, fromthe top bar menu, to the last option (right position mark as green):
It opens a windows to set the flow process with the options:
Can it solve for you? the icons will be changed with a sign too. I didn’t test yet, but it goes throw your process desire, not?
many thanks for your answers!
First I tested the possibility if the desired job-manager will be part of modern-ui. I never used modern-ui, because I am very familiar with Eclipse-IDE. Doesn’t matter, I tested Ipazins suggestion, but … no success. The streming-job-manager won’t be part of modern-ui-package, I think.
Second I try the possible Solution of denisfi. You’re right, I can choose and change between different job-managers as you described. But it is just another way to the same dialog I will reach via the configuration dialog of the node. Only installed / avaiable job-manages can be selected and that’s exactly my problem.
I read your answer once more. You’re right! I missunderstood, I am sorry. Not “KNIME Modern-UI”, but “KNIME Testing Framework UI” and … that’s it!
Thank you very much!
You are welcome Ingo @ingo_knime
