> It would be very useful to have a command that we could give a hdfs directory
> to, that would use fsck to find the block locations of the data files in that
> directory and group them by host and display the distribution graphically. We
> did this by hand and it was very for finding a skewed distribution that was
> causing performance problems. The tool should also be able to group by rack
> id and generate a similar plot.
