Attribute

ProxyUser (PU)

Purpose

Specifies the UserID used for Kerberos authentication, HiveServer2 Impersonation and Trusted Impersonation. When authentication or 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 Kerberos authentication and impersonation are disabled, you will execute queries as the default user for the server.

Kerberos authentication and impersonation provide a method for administrators to control access to data. Administrators set access rights to files by using HDFS and directory permissions on the server.
Note: HiveServer2 Impersonation and Trusted Impersonation are not currently supported by Spark SQL.
