> Often there are cases of a region not getting assigned due to timeouts (while others
do go through). In this case, the Master does appear to enter a never-ending retry operation
where it retries each chosen server several times before moving to another.
> For debugging in such a scenario, where the master is best aware of the situation, it
could use that to its advantage and help capture issues better if it probably setup an N retry
threshold (for # of servers tried) and run a HTTP GET on the current timing out RS's info
port, to capture its /stacks end point and dump the output in its logs for investigation later.
