    • Type: Bug

    • Priority: Major
    • Resolution: Fixed
    • Affects Version/s: None
    • Fix Version/s: 3.0.0-alpha1
    • Component/s: None
    • Labels:
      None
    • Hadoop Flags:
      Incompatible change, Reviewed
    • Release Note:
      Yarn now only issues and allows delegation tokens in secure clusters. Clients should no longer request delegation tokens in a non-secure cluster, or they'll receive an IOException.

      Description

      ClientRMService#getDelegationToken is currently returning a delegation token in insecure mode. We should not return the token if it's in insecure mode.
