Ewan Higgs updated HDFS-13118:
             Assignee: Ewan Higgs
    Affects Version/s: 3.0.0
               Status: Patch Available  (was: Open)

Added a patch that adds the INodeType to the SnapshotDiffReport. This will make 
it easier to make programatic comparisons between sides of a snapshot. This 
includes a new field in the profobuf: {{fileType}} that reuses the existing 
enum from the {{HdfsFileStatusProto}}. This field is optional with the 
intention of being backwards compatible.

This does not change the printed output of the command line for

> Currently the snapshot diff report will list which inodes were added, 
> removed, renamed, etc. But to see what the INode actually is, we need to 
> actually access the underlying snapshot - and this is cumbersome to do 
> programmatically when the snapshot diff already has the information.
