First thing you would need to do is to update from 4.2 to 4.4.2 NB1.
To do this, download the NB1 tar file in note 4 and flash with Odin.
To root 4.4.2, download Towel Root apk, install it on your phone and run it (make it rain). Then download SuperSU from Play Store and let it update its binary.
thanks..just to summarize I am giving yr instructions and my compliance/clarifications before I proceed. Please let me know if anything is missing

You can begin the following process from any 4.4.x Build/ROM or higher but you must already have Root Access*--- yes I have 4.4. . (not 4.2 as I wrongly mentioned)
. If you are not already rooted (or to unbrick) you must first flash the I337UCUFNB1_Rootable_Full_Odin.tar (use Odin's PDA slot (AP in Odin v3.09+), root with Towelroot, then proceed with the above process. -done

1. The above process will not affect your Knox Warranty Flag.- when I used SU it said that KNOX is removed .

3. No need to wipe prior to flashing! The ROM will automatically perform a factory data reset
