ASF GitHub Bot commented on DRILL-6332:
---------------------------------------
j-4 commented on pull request #1931: Fixes DRILL-6332 by allowing to provide
two-component principals
URL: https://github.com/apache/drill/pull/1931
Currently drill only allows for three-component kerberos principals
`primary/instance@REALM`
I had the requirement to deal with two-part principals `primary@REALM` and
thus made these little changes to the principal checks. This enables drill to
deal with two- and three-part principals.
Behaviour: The principal splitting function will return an empty string for
`instance` if only a two-component principal is given.
