    • Accessing kerberos secured WebHDFS without SPnego

    Accessing kerberos secured WebHDFS without SPnego

    Use Case and Business Need

    I have a working application for managing HDFS using WebHDFS. I need to be able to do this on a Kerberos secured cluster.

    The problem is, that there is no library or extension to negotiate the ticket for my app, I only have a basic HTTP client.

    Would it be possible to create a Java service which would handle the ticket exchange and once it gets the Service ticket to just pass it to the app for use in a HTTP request? In other words, my app would ask the Java service to negotiate the tickets and it would return the Service ticket back to my app in a string or raw string and the app would just attach it to the HTTP request?
