Zhe Zhang commented on HDFS-7826:
---------------------------------
Oops I didn't realize this JIRA handles {{computeFileSize}}. I was about to
suggest the following code under HDFS-7749.
{code}
public final long computeFileSize(boolean includesLastUcBlock,
boolean usePreferredBlockSize4LastUcBlock) {
BlockInfo[] blocksInfile = isStriped() ?
getStripedBlocksFeature().getBlocks() : blocks;
if (blocksInfile == null || blocksInfile.length == 0) {
return 0;
}
final int last = blocksInfile.length - 1;
//check if the last block is BlockInfoUnderConstruction
long size = blocksInfile[last].getNumBytes();
if (blocksInfile[last] instanceof BlockInfoContiguousUnderConstruction ||
blocksInfile[last] instanceof BlockInfoStripedUnderConstruction) {
if (!includesLastUcBlock) {
size = 0;
} else if (usePreferredBlockSize4LastUcBlock) {
size = getPreferredBlockSize();
}
}
//sum other blocks
for(int i = 0; i < last; i++) {
size += blocksInfile[i].getNumBytes();
}
return size;
}
{code}
> 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.
