I am using Rapidminer server 8.2
I have developed custom extension for rapidminer and tested it on RM Studio and RM Server.
I was able to run the plugin on RM Studio and RM Server for first time.
After I made some changes to the extension code and tried to run again on server it is showing dummy operator error:(com.rapidminer.operator.DummyOperator.doWork(DummyOperator.java:94)
Steps I did to install plugin:
- tried to delete the previous extension and copied new jar file in the server plugins directory, but it is still showing same error
- tried to restart the server and redo the process again.
- Is there a way in which I can include something in extension code to tell rapidminer server to refresh the plugins folder or look again for new plugin...?
- Is the restart of whole server required to install one new plugin ..?
Any suggestions why is this problem is coming...
