Configuring User Authentication

Mar 16, 2017

Authentication is the process of establishing confidence of authenticity. A Drill client user is authenticated when a drillbit process running in a Drill cluster confirms the identity it is presented with. Drill 1.10 supports several authentication mechanisms through which users can prove their identity before accessing cluster data:

These authentication options are available through JDBC and ODBC interfaces.


Note

If user impersonation is enabled, Drill executes the client requests as the authenticated user. Otherwise, Drill executes client requests as the user that started the drillbit process. You can enable both authentication and impersonation to improve Drill security. See Configuring User Impersonation for more information.
