Zhe Zhang edited comment on HDFS-10534 at 11/15/16 12:30 AM: ------------------------------------------------------------- Thanks Kai again for the work, and sorry for the late review. I actually didn't find an easier way to generate histogram from dust. The histogram looks pretty nice! I only have 2 minot concerns: # It is a little too wide and requires scrolling to the right to view the full picture. Meanwhile, i think each bar can be narrower which should save space to display the whole picture. # Can we have 10% etc. instead of 0.1 etc? +1 pending the above.
