The hadoop package introduced new or modified debconf templates. This is the perfect moment for a review to help the package maintainer following the general suggested writing style and track down typos and errors in the use of English language. If someone wants to pick up this review, please answer to this mail, in the mailing list, with an [ITR] (Intent To Review) label. The templates file is attached. To propose the file you reviewed for peer review, please send a [RFR] (Request For Review) mail with the reviewed file attached...then a few days later, when no more contributions come, a summary mail with a [LCFC] (Last Chance For Comments) label. Finally, after no more comments coming to the LCFC mail, you can send the reviewed templates file as a bug report against the package. Then, please notify the list with a last mail using a [BTS] label with the bug number. Helping the package maintainer to deal with induced translation updates at that moment will be nice. If you're not comfortable with that part of the process, please hand it off to a translator. --
Template: hadoop-namenoded/format Type: boolean Default: false _Description: Should the namenode's filesystem be formatted now? The namenode manages the Hadoop Distributed FileSystem (HDFS). Like a normal filesystem, it needs to be formatted prior to first use. If the HDFS filesystem is not formatted, the namenode daemon will fail to start. . This operation does not affect the "normal" filesystem on this computer. If you're using HDFS for the first time and don't have data from previous installations on this computer, it should be save to proceed with yes. . You can later on format the filesystem yourself with . su -c"hadoop namenode -format" hadoop

Description: software platform for processing vast amounts of data
This package contains the core java libraries.
Package: libhadoop-index-java

Depends: ${misc:Depends}, libhadoop-java (= ${binary:Version}),
liblucene2-java
Description: 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.

Description: 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.
Package: hadoop-daemons-common
Section: misc
Architecture: all
Depends: ${misc:Depends}, hadoop-bin (= ${binary:Version}), daemon, adduser,
lsb-base (>= 3.2-14)
Description: 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
Package: libhadoop-java-doc
Section: doc
Architecture: all
Depends: ${misc:Depends}, libhadoop-java (= ${binary:Version})
Description: Contains the javadoc for hadoop

Package: hadoop-tasktrackerd
Section: misc
Architecture: all
Depends: ${misc:Depends}, hadoop-daemons-common (= ${binary:Version})
Description: 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.
Package: hadoop-jobtrackerd
Section: misc
Architecture: all
Depends: ${misc:Depends}, hadoop-daemons-common (= ${binary:Version})
Description: 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.
Package: hadoop-namenoded

Description: 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.
Package: hadoop-secondarynamenoded
Section: misc
Architecture: all
Depends: ${misc:Depends}, hadoop-daemons-common (= ${binary:Version})
Description: 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.
Package: hadoop-datanoded
Section: misc
Architecture: all
Depends: ${misc:Depends}, hadoop-daemons-common (= ${binary:Version})
Description: 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.
