[SPARK-22319][Core] call loginUserFromKeytab before accessing hdfs ## What changes were proposed in this pull request? In `SparkSubmit`, call `loginUserFromKeytab` before attempting to make RPC calls to the NameNode. ## How was this patch tested? I manually tested this patch by: 1. Confirming that my Spark application failed to launch with the error reported in https://issues.apache.org/jira/browse/SPARK-22319. 2. Applying this patch and confirming that the app no longer fails to launch, even when I have not manually run `kinit` on the host. Presumably we also want integration tests for secure clusters so that we catch this sort of thing. I'm happy to take a shot at this if it's feasible and someone can point me in the right direction.
