Hadoop Distributed File System

Kerberos Authentication

Kerberos support for reading and writing to HDFS is available via the Input Data, Output Data, Connect In-DB, and Data Stream In tools. There are three Kerberos options in the HDFS Connection window. The option you choose depends on how your IT admin configured the HDFS server:

• None: No authentication is used.
• Kerberos MIT: Alteryx will use the default MIT ticket to authenticate with the server. You must first acquire a valid ticket using the MIT Kerberos Ticket Manager.
• Kerberos SSPI: Alteryx will use Windows Kerberos keys for authentication, which are obtained when logging in to Windows with your Windows credentials. The User Name and Password fields are therefore not available.
