Ruslan Dautkhanov created SPARK-19143:
-----------------------------------------
Summary: API in Spark for distributing new delegation tokens (Improve delegation token handling in secure clusters)
Key: SPARK-19143
URL: https://issues.apache.org/jira/browse/SPARK-19143
Project: Spark
Issue Type: Improvement
Components: Spark Core, YARN
Affects Versions: 2.1.0, 2.0.2
Reporter: Ruslan Dautkhanov
Spin off from SPARK-14743 and comments chain in [recent comments| https://issues.apache.org/jira/browse/SPARK-5493?focusedCommentId=15802179&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15802179] in SPARK-5493.
Spark currently doesn't have a way for distribution new delegation tokens. Quoting [~vanzin] from SPARK-5493

IIRC Livy doesn't yet support delegation token renewal. Once it reaches the TTL, the session is unusable.
There might be ways to hack support for that without changes in Spark, but I'd like to see a proper API in Spark for distributing new delegation tokens. I mentioned that in SPARK-14743, but although that bug is closed, that particular feature hasn't been implemented yet.
