He Xiaoqiao commented on HDFS-14771:
------------------------------------
thanks [~kihwal],[~sodonnell] for your discussions. it seems I misunderstand
what fsimage layout version. based on above comments, layout version need to
change only when meet incompatibility rather than any format changes, right?
for branch-2 backport, I am testing but not finished. until now some test case
i ran (not include OIV test case), it seems work well, and no any reproduce
exception. I will attach result once when test finish. Thanks again.
