if (removedDst != null) {
undoRemoveDst = false;
if (removedNum > 0) {
BlocksMapUpdateInfo collectedBlocks = new BlocksMapUpdateInfo();
List<INode> removedINodes = new ChunkedArrayList<INode>();
filesDeleted = removedDst.cleanSubtree(Snapshot.CURRENT_STATE_ID,
dstIIP.getLatestSnapshotId(), collectedBlocks, removedINodes,

getFSNamesystem().removePathAndBlocks(src, collectedBlocks,
removedINodes, false);
