Luke Lu commented on HADOOP-9700:
---------------------------------
The patch uses SnapshotDiffReport, which only supports granularity of diff at
file level. One use case we should support is the file append/flush case, where
only newly appended blocks should be copied and concated to the previous
snapshot on the remote side. Maybe we should to use SnapshotDiffInfo directly?
