Jing Zhao commented on HDFS-7826:
---------------------------------
So I think we may need to update several places for quota and file size
computation:
# {{computeFileSize(boolean, boolean)}} currently only takes into account the
contiguous block for the last block. Similar for
{{storagespaceConsumedNoReplication}}. We should also consider the
BlockInfoStripedUC in these places.
{code}
if (blocks[last] instanceof BlockInfoContiguousUnderConstruction) {
if (!includesLastUcBlock) {
size = 0;
} else if (usePreferredBlockSize4LastUcBlock) {
size = getPreferredBlockSize();
}
}
{code}
# The {{storagespaceConsumed}} method also only works for contiguous blocks
since it uses {{getBlockReplication}}
> Erasure Coding: Update INodeFile quota computation for striped blocks

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