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

Github user ShawnWalker commented on the issue:

    https://github.com/apache/accumulo/pull/121
  
    If the tablet server returns before master notices it's gone, master will see it as a
new empty tablet server.  This will (usually) cause balancing to be run, to give that tserver
some work.  Once master notices that the original tserver has died, the original tserver's
tablets will move to `TabletState.SUSPENDED`, and (assuming a sufficiently large `tablet.suspend.duration`),
those suspended tablets will shortly be assigned to the "new" tserver.  This will again cause
imbalance, as the "new" tserver will have approximately double it's expected load, causing
yet more round(s) of balancing.
