Distributed Executors

#1

Hi KNIME,

I have a question.

I want to construct Distributed Executors but I encountered this error.

How should I do?

Multiple Executors on the same machine

Hi,

which KNIME Server version do you use?
There has been a bug in KNIME Server 4.8.2 and lower where you could encounter this problem. To solve this, simply restart KNIME Server (keep RabbitMQ running) and then it should work.
This behavior should have been fixed with KNIME Server 4.8.3 and KNIME Server 4.9.1.

Cheers,
Moritz

Actually in this particular case it looks more like the KNIME Server version and the KNIME Executor version don’t match.

Thanks, @moritz.heine and @thor

Sorry for the late reply. It was a holiday season in Korea.

I’m going to try like what you guys said and to inform how the result is.
(my Server version is 4.8.0)

Thank you guys,

It was the problem of KNIME Executor version.

I had a KNIME Executor v_3.7.1 on one machine installed the KNIME Server and other KNIME Executor v_3.7.2 on the other machine only for KNIME Executor.

I synchronized the version of Executors as v_3.7.1 and it was succeeded to construct the Distributed Executor.

Thank you guys for your reply, @moritz.heine and @thor.

Best,
