Hadoop execution sequence

I was wondering if hadoop performs the map reduce operations on the data in
maintaining he order or sequence of data in which it received the data.
I have a hadoop cluster that is receiving json files.. Which are processed
and then stored on base.
For correct calculation it is essential for the json files to be processed
on the order they are received. How can I make sure this happens.

Thanking you,
