> Key: FLINK-1702
> URL: https://issues.apache.org/jira/browse/FLINK-1702
> Project: Flink
> Issue Type: Improvement
> Components: Security
> Reporter: Maximilian Michels
> Priority: Minor
> Fix For: 1.0.0
>
>
> 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.
