Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Lucene-hadoop Wiki" for change notification.

The following page has been changed by OwenOMalley:

- [http://lucene.apache.org/hadoop/ Hadoop] is a framework for managing applications across
large clusters of information in such a way that the application does not need to worry about
either reliability or locality. Hadoop uses a computational paradigm named [:HadoopMapReduce:
Map/Reduce], where the application is divided into many fragments of work, each of which may
be executed or reexecuted on any computer in the cluster. To support locality-transparency,
Hadoop stores persistent data in a distributed file system that is designed for large streaming
reads and fault tolerance.
+ [http://lucene.apache.org/hadoop/ Hadoop] is a framework for running applications on large
clusters built of commodity hardware. The Hadoop framework transparently provides applications
both reliability and data motion. Hadoop implements a computational paradigm named [:HadoopMapReduce:
Map/Reduce], where the application is divided into many small fragments of work, each of which
may be executed or reexecuted on any node in the cluster. In addition, it provides a distributed
file system that stores data on the compute nodes and thereby provides very high aggregate
bandwidth across the cluster. Both Map/Reduce and the distributed file system are designed
so that node failures are automatically handled by the network.
  
  The intent is to scale Hadoop up to handling thousand of computers. The current high water
marks that have been reported are:
   * !DataNodes: 620
