We’re making sure all the nodes up, when we run it. I don’t believe we are 
using LOCAL_XXX and the repair was being planned to be run only on local DC 
since that was where the node was down. Do we need to run a full cluster repair?

If there was no node down during that period, and you are using LOCAL_QUORUM 
read/write, then yes above command works.

Hi –
  I have a question on running a repair after bringing up a node that was down 
(brought down gracefully) for a few days within a data center. Can we just run 
nodetool repair –dc <DC> on a single node (within that DC – specifically the 
downed node, after it is brought online) and have that entire DC repaired?

Regards,
Dhruva
