@harishreedharan I'm pretty sure the --keytab and --principal options
still work in client mode to SparkSubmit. Its simply the way it passes it on to
the client. in yarn client mode it uses the config and in yarn cluster mode it
uses the command line options.
OptionAssigner(args.principal, YARN, CLIENT, sysProp =
"spark.yarn.principal"),
OptionAssigner(args.keytab, YARN, CLIENT, sysProp = "spark.yarn.keytab"),
I'm building now and will test it to double check. Did you try it
yourself?
That would not be a blocker for 1.4 though. We would revert and fix.
