I installed the KNIME Expressions extension and now all of a sudden, KNIME does not start anymore. It shows the splash screen for minutes (we’re talking like 30+ minutes), no extension icons are loaded in the splash screen and the application itself does not open anymore.
Any idea how to overcome this?
What I have done already: Secured my workspace and deleted also the .metadata folder in the workspace.
I had that issue several times recently, it seems to happen with newer KNIME versions – in my case, the KNIME application eventually always opened after waiting really, reaaaaaaaaaaaaaally long. Once it was a matter of approx. 15 minutes, once it literally took “a lunch break”. In any case, just waiting seemed to help, and the following restarts were back to normal pace.
I don’t know what’s going on behind the curtains, not to mention any cure, but I can confirm that it happened after installing or updating extensions.
So I basically uninstalled and re-installed now 4.6.3 (the problematic one was 4.6.2 and the extension I wanted to install was the KNIME Expressions - containing the Column Expressions Node).
Now I have SE Nodes (@qqilihq ), Vernalis, Palladian, KNIME Reporting (BIRT) installed and all works again.
@qqilihq Eventually I have to wait a little bit longer in the future, some say, I am to hectic
