Hi Kumar,
I believe right now there is no way to directly generate the DDL statement
for the existing table,better to write down you sql immedately after
exection (in oracle ,dbms_metadata is so perfect ,in hive show create
table also works )
however you can query system.catalog for all the information you need .
