> Fix file quota change when converting a file with striped blocks from
> complete/under-construction to under-construction/complete state. When we add
> a new block (FSDirectory#addBlock) we update the quota using the full block
> size (since we do not know how much data the user will write to
> the new block), and when we complete/commit the block, the quota is updated
> based on the block's real size (FSNamesystem#commitOrCompleteLastBlock).
> Currently these two places only support contiguous blocks (using
> INodeFile#getPreferredBlockSize as the full block size). We should update
> them for striped blocks.
