Konstantin Shvachko commented on HDFS-5464:
-------------------------------------------
> you won't argue that the new code is simpler than the existing
Agreed on simpler. :-)
> see if I could come up a better solution
Sure would be interesting to see. I doubt much can be done in this respect. We
need to find blocks that did not appear in the report: in one pass and with
constant memory overhead. May be an interview question.
> Simplify block report diff calculation

> The current calculation in BlockManager.reportDiff(..) is unnecessarily
> complicated. We could simplify the calculation.
