> FLINK-1504 implemented support for Kerberos authentication for HDFS in Flink. Currently,
the authentication has to be performed on every node when the job or task manager comes up.
That implies that all nodes are already authenticated using Kerberos.
> For the Hadoop security mechanism it would be sufficient if the Client authenticated
once using Kerberos and received the Hadoop DelegationToken. This Token could then be passed
to all nodes. It would be renewed using the Hadoop security mechanisms.
