Kevin Minder commented on KNOX-180:
-----------------------------------
Hi Amit,
I'm not certain what you are asking. If you could expand on the actual
use case you are targeting for Hive, Pig, Scoop, etc. I can probably
provide better guidance. At the highest level all I can say is that the
approach for Hive and Pig will be very similar as they will both use
WebHCat. Scoop is an entirely different matter.
Kevin.
