> support zero-keytab Oozie application launch via HADOOP_TOKEN_FILE_LOCATION env var

>                 Key: SPARK-13148
>                 URL: https://issues.apache.org/jira/browse/SPARK-13148
>             Project: Spark
>          Issue Type: New Feature
>          Components: YARN
>    Affects Versions: 1.6.0
>         Environment: YARN cluster with Kerberos enabled, launched from Oozie —where Oozie passes down the delegation tokens
>            Reporter: Steve Loughran
>
> Oozie can launch Spark instances on insecure clusters, and on a secure cluster if Oozie is set up to provide a keytab.
> What it cannot currently do is launch a Spark application on a YARN cluster without a keytab. In this situation, Oozie collects the delegation tokens it is setup to collect (as a superuser in the cluster), saves them to a file, then points to the file in the `HADOOP_TOKEN_FILE_LOCATION` environment variable.
> These tokens need to be used to launch the application —rather than try to get some more
