Robert Joseph Evans commented on MAPREDUCE-5379:
------------------------------------------------
I am not sure how to actually do this. On some systems there may be multiple
File Systems and hence there may be multiple delegation tokens. Think ViewFS
with federation.
> Include FS delegation token ID in job conf
