> 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.
