Arpit Agarwal updated HDFS-5515:
--------------------------------
Attachment: h5515.02.patch
# Add DatanodeUuid initialization in
{{UpgradeUtilities#createDataNodeVersionFile}}. trunk initialized the
equivalent storageID in the same location.
# Remove spurious check in {{DataStorage#setPropertiesFromFields}}.
New protocol compatibility tests to ensure NN-DN compatibility in the absence
of DatanodeUuid will be added separately.
