Subject Can column type be changed dynamically?
Date Fri, 27 Apr 2012 15:26:10 GMT
Hi all,

I want to change one of my column type from IntegerType to Int32Type
dynamically. I'm sure all datas in that column are int32 type indeed. So I
want changing the column type by:

*update column family XXX with column_metadata = [{column_name : 'xxx',
validation_class : Int32Type}];*

Is there any harm to do this?
