Tsz Wo (Nicholas), SZE updated HDFS-4441:
-----------------------------------------
Attachment: h4441_20130125.patch
h4441_20130125.patch:
- Keeps Pair unchanged, i.e. leave it in INode.
- Renames other classes.
- For DEFAULT_ARRAY_INITIAL_CAPACITY, I tried to add /** initial array
capacity. */ but removed it since the name was already clear about it.
- Also fixes a bug in INode.dumpTreeRecursively(..) that it casts this to
INodeFileSnapshot but this could be a INodeFileUnderConstructionSnapshot.
{code}
if (this instanceof INodeFileSnapshot
|| this instanceof INodeFileUnderConstructionSnapshot) {
out.print(", computedSize="
+ ((INodeFileSnapshot) this).computeFileSize(true));
}
{code}
> Refactor INodeDirectoryWithSnapshot.Diff as a top level generic class

> INodeDirectoryWithSnapshot.Diff is for recording the difference between the
> current state and a previous state of the children list of an INodeDirectory.
> It is easy to refactor the code to support generic lists.
