Hi,
I think this problem tracked in this issue:
https://issues.apache.org/jira/browse/FLINK-3670 . This means that the
current master and upcoming release 1.2 should work correctly.
Best,
Stefan

Hi everyone,
I'm using Flink 1.1.3 with Hadoop 2.7.3 and was wondering about
delegation token renewal when running Flink on Yarn. Yarn demands
services to renew delegation tokens on their own and if not, Yarn
jobs will fail after one week.
https://hadoop.apache.org/docs/current/hadoop-yarn/hadoop-yarn-site/YarnApplicationSecurity.html
For example, Spark has implemented a solution for that
https://github.com/apache/spark/blob/v2.0.1/yarn/src/main/scala/org/apache/spark/deploy/yarn/AMDelegationTokenRenewer.scala
and people had reported issues running Flink in the past,
http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/Flink-job-on-secure-Yarn-fails-after-many-hours-td3856.html
What is the status of this issue? How can Flink on Yarn handle this
issue so that jobs do not fail due to token expiration?
Cheers,
Theo
