Hudson commented on ACCUMULO-879:

Integrated in Accumulo-Trunk #571 (See [])
    ACCUMULO-879 Shaved ~1sec off Accumulo statup time by reacting to new tservers using zookeeper
watchers (Revision 1419712)

     Result = SUCCESS

> I have looked a little bit into where the time is going when starting MiniAccumuloCluster,
but I have not looked into how it could possibly be sped up.
> First a ZooKeeper server is started and then Accumulo initialize is run.   This takes
about 1 second.   After this a master and tablet server are started.  It takes ~2 seconds
from the time the tablet server starts until the root tablet is assigned.  I think these two
places are where the bulk of the startup time is currently spent.
