Keith Turner commented on ACCUMULO-2998:
----------------------------------------

[~ecn] and I had an offline discussion about this issue.  A few points that I 
think are interesting

 * The little test utility I wrote waits for tablets to be evenly spread, but 
this makes assumptions about how the pluggable balancer behaves.  [~ecn]'s 
changes are more general and wait until the pluggable balance has no more work 
to do.   
 * The method waits for the entire system to be balanced.  I was thinking it 
may be more useful to wait for a particular table to be balanced.  However, the 
use does not have to use the per table balancer making it tricky to implement 
waiting for a particular table to balance.

> provide a mechanism to allow clients to wait for balance

> It would be nice to wait for the balancer to run and find no work to do after 
> creating a bunch of splits.
