Null Representation in Hive tables

[mahender bigdata]

Hi,

Is there any possibility of mentioning 
both*"serialization.null.format"=""  and 
**"serialization.null.format"="\000" *has table properties, currently we 
are creating external table, where there is chance of having data with 
empty string or \000, As a  work around, we have created 2 external 
tables, one with "serialization.null.format"="" has table property and 
another with "serialization.null.format"="\000" where we insert data 
from external table 1 to table 2. Is there way to reduce to single step 
having mentioning both *"serialization.null.format"="" and 
**"serialization.null.format"="\000"*in the same table property.

Thanks,
Mahender
