I have a table with about 2.000.000 rows. I try to run the decision tree learner with that table. While the node is running I get the following messages:
WARN KNIMEApplication$4 Potential deadlock in AWT Event Queue detected. Full thread dump will follow as debug ouput.
WARN KNIMEApplication$3 Potential deadlock in SWT Display thread detected. Full thread dump will follow as debug ouput.
The node is running till 74% reached. Then the node breaks down and I get this message:
ERROR Decision Tree Learner 5:538 Execute failed: ("RuntimeException"): null
Can anybody help me? I think it is because of the big table. But are there any possibilities to process the table?
Thanks for your help!
