Saisai Shao commented on SPARK-16742:
-------------------------------------
The proposed solution is quite different from what existed in Spark on YARN.
IIUC this solution looks doesn't honor delegation token, and wraps every HDFS
operation with {{executeSecure}}, I simply doubt that this approach requires
other components, like sql, streaming, should also know the existence of such
APIs and try to wrap them. Also if newly added codes ignore this wrapper, this
will lead to error. From my understanding it is quite intrusive.
