Todd Lipcon commented on HDFS-2538:
-----------------------------------
Given we know how many files/blocks/whatevers we have in the namespace before
we even start the operation, maybe we can just make the dot frequency relative
to that? eg print a dot for every 1% or 5% so you just get a line or two, but
still have some indication of progress?
> option for fsck dots to be on/off

> this patch turns the dots during fsck off by default and provides an option
> to turn them back on if you have a fetish for millions and millions of dots
> on your terminal. i haven't done any benchmarks, but i suspect fsck is now
> 300% faster to boot.
