Databricks Certified Data Engineer Professional Exam - Topic 3 Question 20 Discussion

[All Databricks Certified Data Engineer Professional Questions]

What is a method of installing a Python package scoped at the notebook level to all nodes in the currently active cluster?

Show Suggested Answer Hide Answer
Suggested Answer: C

Installing a Python package scoped at the notebook level to all nodes in the currently active cluster in Databricks can be achieved by using the Libraries tab in the cluster UI. This interface allows you to install libraries across all nodes in the cluster. While the %pip command in a notebook cell would only affect the driver node, using the cluster UI ensures that the package is installed on all nodes.

I definitely recall that activating an environment in a notebook setup script is not the usual way to install packages for all nodes.

I think using pip install in a notebook cell sounds familiar, but I'm not entirely sure if it applies to all nodes in the cluster.

Hmm, I'm not sure about that. I think option C might be the way to go - installing directly from PyPi using the cluster UI seems like the most straightforward approach.

I'm pretty confident that the correct answer is B. Running the activate script in a setup notebook should install the package across the cluster.

I'm a bit confused by the wording of this question. What exactly do they mean by "scoped at the notebook level"? I'll need to re-read that part carefully.

Okay, let's see. I think the key here is that the package needs to be installed at the notebook level and across all nodes in the cluster. That rules out a few of these options.
