You will incur the cost of map reduce across all nodes in your cluster anyways. Not sure, you
will get enough speed advantage.
HBase may help you get close to what you are looking for but that wont be map reduce.

Thanks,

Subject: Binary Search in map reduce

Hi,
 I have data in json format like:

{key:[values.....]}
key, values are longints.
Now, I want to do a fast lookup of a key.
How would I implement a binary search in map reduce abstraction.

Or am i not thinking about this correctly?
Any suggestions/advices?
Thanks
