(new) hadoop-bin_0.20.1+dfsg1-1_all.deb optional java
hadoop command line interface
brings the shell script hadoop
(new) hadoop-daemons-common_0.20.1+dfsg1-1_all.deb optional java
creates user and directories for hadoop daemons
* creates the user hadoop
* creates data and log directories owned by the hadoop user
* manages the update-alternatives mechanism for hadoop configuration
* brings in the common dependencies
(new) hadoop-datanoded_0.20.1+dfsg1-1_all.deb optional java
Data Node for Hadoop
The Data Nodes in the Hadoop Cluster are responsible for serving up
blocks of data over the network to Hadoop Distributed Filesystem
(HDFS) clients.
(new) hadoop-jobtrackerd_0.20.1+dfsg1-1_all.deb optional java
Job Tracker for Hadoop
The jobtracker is a central service which is responsible for managing
the tasktracker services running on all nodes in a Hadoop Cluster.
The jobtracker allocates work to the tasktracker nearest to the data
with an available work slot.
(new) hadoop-namenoded_0.20.1+dfsg1-1_all.deb optional java
Name Node for Hadoop
The Hadoop Distributed Filesystem (HDFS) requires one unique server, the
namenode, which manages the block locations of files on the filesystem.
(new) hadoop-secondarynamenoded_0.20.1+dfsg1-1_all.deb optional java
Secondary Name Node for Hadoop
The Secondary Name Node is responsible for checkpointing file system images.
It is _not_ a failover pair for the namenode, and may safely be run on the
same machine.
(new) hadoop-tasktrackerd_0.20.1+dfsg1-1_all.deb optional java
Task Tracker for Hadoop
The Task Tracker is the Hadoop service that accepts MapReduce tasks and
computes results. Each node in a Hadoop cluster that should be doing
computation should run a Task Tracker.
(new) hadoop_0.20.1+dfsg1-1.debian.tar.gz optional java
(new) hadoop_0.20.1+dfsg1-1.dsc optional java
(new) hadoop_0.20.1+dfsg1.orig.tar.gz optional java

Hadoop contrib to create lucene indexes
This contrib package provides a utility to build or update an index
using Map/Reduce.
.
A distributed "index" is partitioned into "shards". Each shard corresponds
to a Lucene instance. org.apache.hadoop.contrib.index.main.UpdateIndex
contains the main() method which uses a Map/Reduce job to analyze documents
and update Lucene instances in parallel.
(new) libhadoop-java-doc_0.20.1+dfsg1-1_all.deb optional doc
Contains the javadoc for hadoop
contains the api documentation of hadoop
(new) libhadoop-java_0.20.1+dfsg1-1_all.deb optional java
software platform for processing vast amounts of data
Hadoop is a software platform that lets one easily write and
run applications that process vast amounts of data.
.
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.
.
Hadoop implements MapReduce, using the Hadoop Distributed File System (HDFS).
MapReduce divides applications into many small blocks of work. HDFS creates
multiple replicas of data blocks for reliability, placing them on compute
nodes around the cluster. MapReduce can then process the data where it is
located.
.
This package contains the core java libraries.
