Zhe Zhang updated HDFS-8195:
----------------------------
    Affects Version/s: HDFS-7285
               Status: Patch Available  (was: Open)

Thanks for working on this Fukudome-san! The overall logic looks good to me.

Attaching v2 patch which is a minor rebase to make it compile. Also triggering 
Jenkins.

{code}
+      final long actualBlockGroupSize =
+          (commitBlock.getNumBytes() / ecSchema.getNumDataUnits()) * numBlocks;
{code}
We should use the {{BlockInfoStriped#spaceConsumed}} logic from HDFS-7949.

> 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.
