Error Unable to find 'msvcr100.dll' at hadoop home creation.

Just started with KNIME and I get this message when the system opens.
I imagine I can find the dll but I’d like advice to the target location.
Win11
Thanks,
Tim

Hi Tim,

Could you please elaborate on how you ran into this issue?
Which version of KNIME Analytics Platform was used, which Nodes/authentication did you use?

Best,
Michael

Hi @MichaelRespondek , I started getting this warning too for a while now. I don’t remember after which extension I installed, but it’s an extension that’s trying to initialize Hadoop.

There is no specific node that generates this warning. I see this warning as soon as my Knime AP is loaded, without any workflow loaded/opened. I appears in the Console:
WARN HadoopInitializer Unable to find 'msvcr100.dll' at hadoop home creation.

I ignore it for now since it’s just a warning and not an error, and also as it’s not impacting anything that I am doing. It would indeed be nice to know what’s causing this.

Thanks @bruno29a for the additional details.
It seems as if the error is raised by a missing org.knime.bigdata.commons.windows which should be a dependency of the “KNIME Big Data Connectors” extension on Windows. Could you please try to install the mentioned extension, this should solve your issues.

If you don’t need HDFS access you could also ignore the error message.

Best,
Michael

No problem @MichaelRespondek .

I don’t really need this extension, nor am I using HDFS, but for the sake of checking for other members, I can confirm that I no longer have this warning after installing the KNIME Big Data Connectors extension:

Thank you for this @MichaelRespondek

Thank you for your confirmation that installing of the KNIME Big Data Connector extension solved the triggering of the warning @bruno29a.
We will try to reproduce the issue and fix it, so that the installation of the extension would not be needed to fix the warning.
Thanks for mentioning it @timh.

@bruno29a and @timh: Could you please tell us the version number of the KNIME Analytics Platform as well as the installed (additional) extensions?
Background: We had a bug regarding the dependencies but it should have been already fixed with version 4.4.2.
Therefore it would be good to see if your issue is caused by a different extension if you are already on a version >= 4.4.2.
Thanks,
Michael

Hi @MichaelRespondek , I’m on 4.5.1 on my side.

I can see the list of my installed extension, but how can I copy the list to show you?

I can show you a screenshot in the mean time:

And these at the bottom (outside the screenshot):
Palladian for KNIME: Additional Hashing Algorithms
Palladian for KNIME: OAuth nodes [BETA]
RDKit Nodes Feature
Vernalist KNIME Nodes

EDIT: Some additional info:
Based on the history, the latest additions were (most recent first):
KNIME Integrated Deployment (BIRT Engine)
Update from 4.5 to 4.5.1
KNIME Image Processing

It could be that one of these changes started giving me that warning message.

Hi @bruno29a

If you select “Installation History” tab, then you can copy the text inside the “Configuration Content” window. Is that what you need ?

Hope it helps.

Hey @aworker , I tried highlighting the list with the mouse, but could not. I would only select 1 line. That’s why I could not copy the list.

However, it looks like CTRL+A works. And I can even do this in the “Installed Software” tab too (same behaviour for highlighting).

But thank you for pointing out that we can copy like this :slight_smile:

Thank you all, I will forward the list of extensions as well as the used KAP version to the developer.
I will get back to you with our findings.
Thanks,

As a remedy, i copied it from the last directory shown to the indicated KNIME directories.
Not elegant but no more warnings.

I meet the same warning while using knime 4.5.2. I try to configure a minimal knime4.5.2 without any BigData-related plugins, and the message appears. Everything works well after installing Big Data Connectors, and the warning disappears.
