hemanthboyina commented on HDFS-14957:
--------------------------------------

In INodeFile : 

for computeQuotaUsage 
{code:java}
 FileWithSnapshotFeature sf = getFileWithSnapshotFeature();
    if (sf == null) {
      counts.add(storagespaceConsumed(bsp));
      return counts;
    }  
    FileDiffList fileDiffList = sf.getDiffs();
    int last = fileDiffList.getLastSnapshotId(); {code}
for calculating spaceConsumed , we consider only the files which exists in 
Snapshot  

for computeContentSummary 

    which basically goes to -> storagespaceConsumedContiguous
{code:java}
 if (sf == null) {
      blocks = Arrays.asList(getBlocks());
    } else {
      // Collect all distinct blocks
      Set<BlockInfo> allBlocks = new HashSet<>(Arrays.asList(getBlocks()));
      DiffList<FileDiff> diffs = sf.getDiffs().asList(); {code}
for calculating space consumed , we are cosidering file which exists in diff(In 
Snapshot) and also the file's getBlocks() 

I think the behaviour is wrong .

Any suggestions ?
