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 hadoop shell interface. See the packages hadoop-.*d
 for the hadoop daemons.
(new) hadoop-daemons-common_0.20.1+dfsg2-1_all.deb optional misc
Creates user and directories for hadoop daemons
 Prepares some common things for all hadoop daemon packages:
  * 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+dfsg2-1_all.deb optional misc
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+dfsg2-1_all.deb optional misc
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+dfsg2-1_all.deb optional misc
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+dfsg2-1_all.deb optional misc
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+dfsg2-1_all.deb optional misc
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.

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+dfsg2-1_all.deb optional doc
Contains the javadoc for hadoop
 contains the api documentation of hadoop
(new) libhadoop-java_0.20.1+dfsg2-1_all.deb optional java
software platform for processing vast amounts of data
 This package contains the core java libraries.
Changes: hadoop (0.20.1+dfsg2-1) unstable; urgency=low
 .
  * New repackaging due to copyright issues and pregenerated autoconf
    stuff.
  * moved hadoop-.* packages from section java to section misc
  * Install default configuration to correct doc directory instead of
    /usr/share/libhadoop-java
  * Check in init.d scripts, whether /usr/share/hadoop/common-init.sh
    exists.
  * Fix classpath in hadoop-wrapper.sh
 .
hadoop (0.20.1+dfsg1-1) unstable; urgency=low
 .
  * Initial release. (Closes: #535861)
