I have a loop that runs over a large number of iterations (order of 100,000)
very quickly. It is nice to do context.setStatus() with an indication of
where I am in the loop. Currently I'm only calling setStatus() every 10,000
iterations because I don't want to overwhelm the task trackers with lots of
status messages. Is this something I should be worried, about or is Hadoop
designed to handle a high volume of status messages? If so, I'll just call
setStatus() every iteration.
