----------------------------------------------------------------

Since it is default off, that should be fine actually.
Do you think that you could include a rudimentary health checker script (one that you find
useful) as an example?

> Similar to MAPREDUCE-211, region server should also have a mechanism to check the health

it should stop itself gracefully.
