Marcelo Vanzin commented on SPARK-5493:
---------------------------------------
bq. Is this possible to use --proxy-user along with --principal + --keytab at
the same time?
It is not and in fact that's a pretty bad idea in general. It would expose the
keytab to the proxied user, which in 99% of the cases is not wanted.
