 Review comment:
   1. query on hive table created using Carbon table with standard hive 
partition is not supported. This can be mentioned as a note.
   2. Reading data with Map datatype is not supported. This can be mentioned as 
a note.

 Review comment:
   1. Some basic info(1 or 2 lines) can be mentioned on what this feature does. 
   2. what interface the user can use to query from hive table can be 
mentioned. 
   3. It needs to be mentioned that carbon jars need to be placed in hive/lib 
folder and yarn/lib folders for this feature to work.
