Íñigo Goiri commented on HDFS-13358:
------------------------------------

Yes, tested with multiple Routers and it works.
However, this was with MapReduce jobs so there was some time for Routers to get 
up to date (a few seconds between job submission and mappers starting).
To do a full test we should check for the tokens in each Router with 
milliseconds of difference.
