Zhe Zhang commented on HDFS-7949:
---------------------------------
Thanks Rakesh for working on this!
The below calculation looks quite complex. Could you explain a little more? Is
it consistent with how file size is calculated in other places?
{code}
+ size += ((p.getBlock().getNumBytes() - 1)
+ / (p.getDataBlockNum() * chunkSize) + 1)
+ * chunkSize * p.getParityBlockNum() + p.getBlock().getNumBytes();
{code}
Would also be better to add a simple test for the change.
> WebImageViewer need support file size calculation with striped blocks
