Uninstall (AEN 4.1.2)

Begin by setting the AEN Functional ID (NFI). The NFI is the username of the AEN Service Account which is used to run all AEN services and is also the username of the AEN Admin account. The NFI may be any name. The default NFI is wakari. The NFI is also often set to aen_admin. The NFI (and AEN Functional Group or NFG) are described in the installation instructions.

Set the NFI with this command:

export AEN_SRVC_ACCT="wakari"

Replace the name wakari with the NFI that was set in your installation of Anaconda Enterprise Notebooks.
