PS6:
This file is used in communication between impalad and catalogd/statestore. 
Please make sure impalads can still work with new/old versions of catalogd and 
statestore. Basically only new fields can be added and should be added at the 
end of a table definition.

PS6, Line 679:   10: optional map<THash128, Types.TIcebergDeletionVector> 
data_path_hash_to_dv
Changing type of field 'data_path_hash_to_dv' from 
map<THash128,TIcebergDeletionVector> to 
map<THash128,Types.TIcebergDeletionVector> in TIcebergContentFileStore might 
break the compatibility between impalad and catalogd/statestore during upgrade
