Specifies the UserID used for Impersonation and Trusted Impersonation. When impersonation is enabled on the server, this value determines your identity and access rights to files when executing queries.

Impersonation provides a method for administrators to control access to data. Administrators set access rights to files by using HDFS and directory permissions on the server.
