Hi Akshaya,
Take a look at the yahoo hadoop tutorial for custom data types.

It's actually quite easy to create your own types and stream them. You can
use the
void readFields(DataInput in);
void write(DataOutput out);
methods to initialize your objects.

You can always pass them as comma delimited strings, which is what you are
already doing with your python streaming code, and then use Text as your
value.
