[SPARK-13148] [YARN] [WIP] zero-keytab Oozie application launch
This patch looks for the env var `HADOOP_TOKEN_FILE_LOCATION`, and if set
skips trying to collect new delegation tokens. Instead it relies on the
environment (i.e. oozie) passing them down...it does list them all to identify
when the oozie configuration forgets something.
It's tagged as a WiP as I haven't tested it yet; I'm currently (elsewhere)
writing a bit of code to collect HDFS and RM tokens and save them to a file,
ready to set up the env var. I could add this code into spark, where it would
be able to use the HBase and Hive reflection logic to add these. This would
just be for testing, to isolate Spark operation from Oozie.
