Subject [GitHub] accumulo issue #121: ACCUMULO-4353: Stabilize tablet assignment during trans...

Github user ShawnWalker commented on the issue:

    Upon further thought, I haven't accounted for the possibility that a tablet server might
return before the master notices it had died.  Such a situation would likely happen during
a rolling restart, and might also happen in the other types of transient failures that have
been discussed.
    
    One solution which suggests itself to me is to block balancing until after the next assignment
run whenever the `LiveTServerSet` contains two distinct tservers at the same location (host+port).
 But that would still leave a minor race condition.
    
    Thoughts?
