ryan rawson commented on HBASE-3507:
------------------------------------

how frequently would you move regions?  Moving a highly loaded region under 
load might be more disruptive than leaving where it is... Using a more 
sophisticated algorithm that uses a decaying moving average over some period of 
time seems like that might have a better impact.  For example do you move a 
region because it gets hot for 30 seconds? 1 minute? 5 minutes? 10 minutes 
even?  I'm not sure where the line is, but it seems like the goal should be to 
move regions for persistent high long term load, not transient spikes.

Thoughts?
