Summary: Kerberos: Improving long-running streaming jobs Key: FLINK-3670 URL: https://issues.apache.org/jira/browse/FLINK-3670 Project: Flink Issue Type: Improvement Components: Command-line client, Local Runtime Reporter: Maximilian Michels We have seen in the past, that Hadoop's delegation tokens are subject to a number of subtle token renewal bugs. In addition, they have a maximum life time that can be worked around but is very inconvenient for the user. As per [mailing list discussion|http://apache-flink-mailing-list-archive.1008284.n3.nabble.com/Kerberos-for-Streaming-amp-Kafka-td10906.html], a way to work around the maximum life time of DelegationTokens would be to pass the Kerberos principal and key tab upon job submission. A daemon could then periodically renew the ticket. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
