Jing Zhao updated HDFS-4126:
----------------------------
Attachment: HDFS-4126.001.patch
Initial patch. Also integrate the fsimage saving/loading into
TestSnapshot#testSnapshot. Still have a bug when handling INodeFileLink and
INodeFileSnapshot, which may cause testSnapshot to fail after running ~10
iterations. Will update the patch after fixing the bug.
