Gabor Somogyi commented on SPARK-30037:
---------------------------------------
What use-case justifies the need to create a maybe several hundred lines of
custom implementation which must be maintained by us?
The whole Spark is depending on Hadoop. Re-inventing the wheel is something
where I don't see the return of investment.
If we really want to avoid the 10 liner in the test maybe we can ask our
friends in Hadoop to add custom krb5.conf possibility.
