Exam DBDEA Topics: jobs Difficulty: medium

A Lakeflow Job's transformations require pandas 2.x. The team has been prototyping on a shared cluster that other teams also depend on, and that cluster has pandas 1.5 pinned — upgrading it would break the other teams' workloads. The job is about to go to production. Where should pandas 2.x be installed for this job?

Options (Reading Mode) Click to filter discussion →
  1. A. On the shared cluster, after warning the other teams and having them retest their pipelines
  2. B. With %pip install at the top of the job's notebook, which fixes the version for every job the same way
  3. C. Nowhere, because pinned libraries are not supported on job clusters, so the code must avoid pandas 2.x
  4. D. On the job's own job cluster, whose library list is isolated from the compute other teams share
