Specifies the UserID used for HiveServer2 Impersonation and HiveServer2 Trusted Impersonation. When impersonation is enabled on the server, this value determines your identity and access rights to files when executing queries. If no value is provided for this option or if impersonation is disabled, you will execute queries as the user who initiated the HiveServer process.
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.
