>
> The way some structs like CreationMetadata, CompactionInfo, ColumnStatistics 
> are defined in hive_metastore.thrift is that these structs are used before 
> they are defined. While this works for the java code which is generated, it 
> does not work for the generated cpp code since Thrift does not use 
> pointer/references to the forward declared classes.
> The easy fix for this would be to reorder the struct definitions in the 
> hive_metastore.thrift so that they are always defined before they are used.
