   I am assuming we do need a V2 implementation for this command. I have made an attempt.
Since i am not entirely familiar with the V2 frame work, i may be missing something. Below
are some details:
   - V2 implementation is constrained by what is supported in createTable. So things like,
location, storage specs etc are not considered.
   - V1 implementation can optionally create a table by pointing to a location specified by
user. Which means it can create a table which is populated with data. V2 implementation creates
an empty table with just the definition from the source table.
   
   Please let me know what you guys think.
