Hi,  Ravindra:
   I read your design documents, why not use the standard hive/spark folder structure, is there any problem if use the hive/spark folder structure？

The datasource api still have a problem that it do not support hybird
fileformat table.
Detail description about hybird fileformat table is in this issue:
https://issues.apache.org/jira/browse/CARBONDATA-1377.

All partitions' fileformat of datasource table must be the same.
So we can't change fileformat to carbodata by command "alter table table_xxx
set fileformat carbondata;"

So I think implement TableReader is the right way.
