Suresh Srinivas updated HDFS-1936:
----------------------------------
Attachment: HDFS-1936.1.patch
Todd, here is the patch I have so far. This does not fix the upgrade failure
yet. Can you look at this early version of the patch, since it is not likely to
change when upgrade issues are fixed.
> Updating the layout version from HDFS-1822 causes upgrade problems.
