> 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.
