-------------------------------------
The test failure is not related to the latest patch.
bq. What could possibly break by removing the dots?
Unfortunately, users may use the scripts to run fsck which assume that dots are
output in the console.
[~kamrul], can you please update the document also? The document is in
hadoop-common-project/hadoop-common/src/site/apt/CommandsManual.apt.vm. I'm +1
once it is addressed.

> 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.
