MapReduce : 
MapReduce is a software framework implemented by Google to support 
parallel computations over large (greater than 100 terabyte) data sets 
on unreliable clusters of computers. This framework is largely taken 
from map and reduce functions commonly used in functional programming
like lisp.
MapReduce implementations have been written in C++, Java and other 
languages.
The Hadoop project [1] is a free open source Java MapReduce implementation.
Phoenix [2] is a shared-memory implementation of MapReduce implemented in C.

Bigtable : 
BigTable is a compressed, high performance, DBMS built on Google File System (GFS),
Chubby Lock Service, and a few other Google programs; it is currently not 
distributed or used outside of Google. It began in 2004[1] and is now used by a 
number of Google applications, such as MapReduce, Google Maps, orkut, etc.
BigTable is a column-oriented database system, with a focus on quick reads for columns.

Hypertable : 
      Hypertable is a high performance distributed DBMS.
Modeled after Google's well known Bigtable project.  Launched Feb 2008.

Hadoop : http://hadoop.apache.org

Apache Hadoop is a Free Java software framework that supports data intensive distributed 
applications running on large clusters of commodity computers. [1] It enables applications 
to easily scale out to thousands of nodes and petabytes of data. Hadoop was inspired by 
Google's MapReduce and Google File System (GFS) papers. Sponsored by Yahoo, Google, etc.
