> The AM communication to HDFS and the localization performed by AM require an authenticated identity or delegation tokens.  However, tokens require quite a bit of management to handle renewal and expiry.  It is preferable to leverage a keytab and authenticate via kerberos in the AM (the login identity) and use that identity for managing the interactions.
