Understanding lustre setup ..
Hello,
I have been reading
http://wiki.lustre.org/images/1/1b/Hadoop_wp_v0.4.2.pdf for setting up
Hadoop over lustre.
Generally in hadoop setup, we have 1 Namenode and various number of datanodes.
If I want to setup the same keeping Lustre as backend, in the document
it is mentioned that:

one is mds/namenode, the rest are

Unable to execute Java MapReduce (Hadoop) code from R using rJava
Hi All,
I have written a Java MapReduce code that runs on Hadoop. My intention is
to create an R package which will call the Java code and execute the job.
Hence, I have written a similar R function. But when I call this function
from R terminal, the Hadoop job is not running. Its just printing few lines
of warning messages and does nothing further. Here is the execution
scenario:

Hadoop Hive output read into R
All,
I am using a pretty crude method to get data out of HDFS via Hive and into R and was curious about alternatives that the group has explored.
Basically, I run a system command that runs a hive statement and writes the returned data to a delimited file. Then, I read that file into an object and continue.
For example:
hive.script <- "select * from orders where date =

Samba 3.0, fuse-hdfs and write problems
Hi folks,
I research at the moment a connection over fuse and samba for
hadoop-cluster. Its my private playground, but I have some issues I can't
figure out why they happen.
I use RHEL5.7, packetlist:
rpm -qa|grep samba
samba-3.0.33-3.29.el5_7.4.x86_64
samba-common-3.0.33-3.29.el5_7.4.x86_64
2 servers, one provides samba-shares and one I use as client.

Large data sets with R (binding to hadoop available?)
Dear R community,
I find R fantastic and use R whenever I can for my data analytic
needs. Certain data sets, however, are so large that other tools
seem to be needed to pre-process data such that it can be brought
into R for further analysis.
Questions I have for the many expert contributors on this list are:
1. How do others handle situations of large data sets (gigabytes,
terabytes)

How to make xapian run in hadoop
Hi all,
We use xapian as the backend of our system. Now the data need be indexed ever-increasing, and the local mode is hard to maintain, so we plan to move the index builder to hadoop. We try to make xapian can be run in hadoop, and now met a problem that there are many seek operations when xapian writes the index files, but the method seek() in hadoop c api only support read, and we blocked by

Using R with Hadoop/Hive for Big Data
Hive <http://hadoop.apache.org/hive/> is a data warehouse infrastructure
built on top of Hadoop that provides tools to enable easy data
summarization, adhoc querying and analysis of large datasets data stored in
Hadoop files. It provides a mechanism to put structure on this data and it
also provides a simple query language called QL which is based on SQL and
which enables users familiar with

Running scripts in hadoop
R-help group,
I'm looking for some assistance on using an R-script to read STDIN from
hadoop.
Example, say I have two tables. One is a student table, the other is a class
roster table (tables join on student_id). Student SAT score is in the
student table, whether the student passed or not is in the roster table.
So to determine if a student passed or failed based on their SAT score, I'd

R and Hadoop Integrated Processing Environment - RHIPE
Hello,
We have created an interface between R and Hadoop so that the user
can, after a fashion, interact with very large datasets
using the Map Reduce programming model. We also use IBM's TSpaces to
implement a shared memory implementation that can be
accessed via R(somewhat like networkspaces). RHIPE uses Rserve to
execute R code.
Some of the functions implemented are:

SVM hadoop
Buenos días,
alguien sabe si hay alguna manera de implementar una máquina de soporte
vectorial (svm) con R-hadoop??
Mi interés es hacer procesamiento big data con svm. Se que en R, existen
los paquetes {RtextTools} y {e1071} que permiten hacer svm. Pero no estoy
segura de que el algoritmo sea paralelizable, es decir, que pueda correr en
paralelo a través de la plataforma R-hadoop.
