Jungtaek Lim commented on SPARK-25501:
--------------------------------------
+1 for this. This should help remedy the needs to pass keytab file to executor
side.
It might be better to have design doc to make clear how it works and how we
will integrate to Spark. I'm also curious we have secure way to transmit token
to tasks/executors.
