Hello, I am new to Knime. I would like to ask you to help with an error that I can’t find any answer to.
I have following part of workflow that is working only after second execution, I think the problem is on DB site, but I can’t get administrator to lookup to this issue.
After first execution Database Connector (legacy) node is throwing me an error below:
“ERROR Database Reader (legacy) 0:146 Execute failed: org.apache.thrift.transport.TTransportException: java.net.SocketTimeoutException: Read timed out”
Second execution result of this node is always fine.
Any suggestions how to handle this? Is there a way to just loop somehow this node to rerun it?
Hi there @Kuba_BD,
welcome to KNIME Community Forum!
Considering you are getting a Read timed out you can try increasing the timeout for database operations and see if that helps.
So go File --> Preferences --> KNIME --> Databases (legacy) and increase timeout value.
Additionally there is Impala Connector node you can try out and also I recommend you to use new DB nodes if possible
If nothing works you can use Counting Loop Start node to run these nodes twice.
Br,
Ivan
