> Reading required columns only in nested structure schema
> Example -
> *Current state* -
> Schema - struct<a:int, b:bigint,c:struct<d:int,e:struct<f:int>,g:string>>
> Query - select c.e.f from t where c.e.f > 10;
> Current state - read entire c struct from the file and then filter because
> "hive.io.file.readcolumn.ids" is referred due to which all the children
> column are select to read from the file.
> Conf -
> _hive.io.file.readcolumn.ids = "2"
> hive.io.file.readNestedColumn.paths = "c.e.f"_
> Result -
> boolean[ ] include = [true,false,false,true,true,true,true,true]
> *Expected state* -
> Schema - struct<a:int, b:bigint,c:struct<d:int,e:struct<f:int>,g:string>>
> Query - select c.e.f from t where c.e.f > 10;
> Expected state - instead of reading entire c struct from the file just read
> only the f column by referring the " hive.io.file.readNestedColumn.paths".
> Conf -
> _hive.io.file.readcolumn.ids = "2"
> hive.io.file.readNestedColumn.paths = "c.e.f"_
> Result -
> boolean[ ] include = [true,false,false,true,false,true,true,false]
