    • Status: Resolved
    • Major
    • Resolution: Fixed

    • applications/distributed-shell, security
    • None

    • Secure cluster with the RM principal listed with a /_HOST entry to be expanded, most common with YARN HA enabled.

    Description

      If the auth_to_local is set to map requests from unknown hosts to nobody, the dist shell app fails. The reason is that the client doesn't translate the _HOST placeholder to the local hostname.
