-----------------------------------------
Summary: Authenticate via Kerberos from the client only
Key: FLINK-1702
URL: https://issues.apache.org/jira/browse/FLINK-1702
Project: Flink
Issue Type: Improvement
Reporter: Maximilian Michels
Priority: Minor
Fix For: 0.9
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.
