Lars Hofhansl commented on HBASE-8099:
--------------------------------------

That's fine I think. It's only an empty map (a few dozen bytes), and it's only 
if there something to failover. It's just easier to read (IMHO) if you prefer 
the other approach that's fine.

By the same logic we the Random could also be per failover worker, although the 
Random constructor does increment an AtomicLong.

Let's get this in soon, so I can spin the next RC.
