| Beschreibung |
Hadoop is a software platform for writing and running applications
that process vast amounts of data on a distributed file system.
.
Here's what makes Hadoop especially useful:
* Scalable: Hadoop can reliably store and process petabytes.
* Economical: It distributes the data and processing across clusters
of commonly available computers. These clusters can number
into the thousands of nodes.
* Efficient: By distributing the data, Hadoop can process it in parallel
on the nodes where the data is located. This makes it
extremely rapid.
* Reliable: Hadoop automatically maintains multiple copies of data and
automatically redeploys computing tasks based on failures.
.
The org.apache.hadoop.contrib.index.main.UpdateIndex library provides
support for managing an index using MapReduce. A distributed "index" is
partitioned into "shards", each corresponding to a Lucene instance.
This library's main() method uses a MapReduce job to analyze documents
and update Lucene instances in parallel.
