Critical Description
To reproduce, start a cluster_run and try to load a sample bucket:

I couldn't run cbcollect_info due to a python related issue, but I attached the cluster_run logs.
Is it possible to add a simple pre-commit validation test that can protect against this? we have hundreds of pre-commit regression tests in Analytics that use sample buckets and every time this happens our tests are blocked. Just last month we encountered this due to MB-48026.
