Install Elastich Search nodes on Knime Server from command line

Dear All,

we are trying to add the elastic search extension (Elasticsearch Reader — NodePit) on our Knime Server.

Since we don’t have graphical access to the server, we are using the knime executable as explained in the server admin guide. Here the command we used:
./knime -application org.eclipse.equinox.p2.director -nosplash -consolelog -r '' -i -d /home/knime/knime_server

This command gives us an error due to missing requirements:
!MESSAGE Missing requirement: Elasticsearch Nodes (me.danielesser.knime.elasticsearch.plugin requires 'osgi.bundle; org.eclipse.core.runtime 0.0.0' but it could not be found
Here the complete log: 1611250463327.log (1.8 KB)

Where can these requirements be downloaded? Has anyone faced the same problem?
Thank you!

Best regards,

Hi @csantoni

it looks like home/knime/knime_server is wrong, this should be the path to the executor installation directory. Can you check this?

(Here is the documentation link, for everyone else searching: KNIME Server Administration Guide )

Hey @csantoni,

Thanks @Iris. Is the -d parameter required at all? I can’t remember I have ever used it when installing nodes via terminal (<= Server 4.10). @csantoni please either remove the parameter or specify it properly and give it another try. Happy to get your feedback.

If this does not help, please drop me a message at and we could try this with a more recent developer build of the ElasticSearch Nodes.

Best regards,

Hi @Iris and @danielesser,
thank you so much for the quick reply!

Yes, we were using the wrong path. The correct one was home/knime/knime_server/knime_executor and in this way the installation is successful!
