Find notebook executing user

Hi g3kuser,

Thank you for reaching out in Microsoft Community Forum.

Please follow below steps to Handle mssparkutils.env.getUserName() with SPNs;

1.mssparkutils.env.getUserName() works for named users, but does not reliably return SPN names.

2.SPNs are service accounts, and not treated as interactive users, so this method may return null or empty.

3.Pass the user or SPN name as a parameter to the notebook when triggered via pipeline or API.

4.Use mssparkutils.env.getExecutionId() to trace the notebook run or log trigger identity externally.

Please continue using Microsoft community forum.
