Copying @dineshg13 's response from #14186:

to clarify, this error message shouldn't stop datadog exporter from reporting metrics or have any other issues. This is happening as the docker image doesn't have required dependencies.

There are few routes we can take.

Classify the warning as info, with additional information that it doesn't impact the exporter. (preferred )

I think you can safely discard this info log.

I am also getting this in Kubernetes running v.80 contrib. Please fix or suppress this message. Thanks.
