Kai Sasaki commented on HDFS-7826:
----------------------------------
Thank you so much for gracious advice but I have a question.
I assume `getNumBytes` returns actual data size even in striped block case. And
each data block size and each parity block size is equal.
What I mean is here.
(getNumBytes() / (dataBlockNum * 64KB) represents the number of chunks in a
data block.
And this number is always same to the number of parity blocks. But is it wrong?
If these numbers are same, `getNumBytes` always returns the actual size
whenever data stripes are full or not.

> Currently INodeFile's quota computation only considers contiguous blocks
> (i.e., {{INodeFile#blocks}}). We need to update it to support striped blocks.
