> Right now our spark integration works on secure clusters by getting delegation tokens and sending them to the executors. Unfortunately, applications that need to run for longer than the delegation token lifetime (by default 7 days) will fail.
> In particular, this is an issue for Spark Streaming applications. Since they expect to run indefinitely, we should have a means for renewing the delegation tokens.
