Inserting the parent Id to the child table
Hi All,
I need your suggestions for the following. I am still learning RoR and
pardon my ignorance.

Table B has student_id as the foreign key to Table A
If I am displaying the list of students and wanted to get individual
students addresses based on their id, is the only option is to get the
id from students controller method list

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

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)

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.
Muchas

SVM hadoop
Hola,
Puedes poner un RStudio en Amazon, poner "caret" y a correr....
No sé si tendrás suficiente con lo que te pueda ofrecer Amazon para tu
problema... creo que sí... ;-)....
O directamente hacerlo aquí, que toda esta instalación ya la tienen hecha:

SVM hadoop
Hola Mª Luz,
Te cuento un poco mi visión:
Lo primero de todo es tener claro qué quiero hacer exactamente en paralelo,
se me ocurren 3 escenarios:
(1) Aplicar un modelo en este caso SVM sobre unos datos muy grandes y por
eso necesito hadoop/spark
(2) Realizar muchos modelos SVM sobre datos pequeños (por ejemplo uno por
usuario) y por eso necesito hadoop/spark para parelilizar estos procesos

Reglas de asociación en un cluster Hadoop
Hola,
Quizás no es el ámbito más apropiado, pero vale la pena intentar.
¿Existe alguna implementación en R del modelo de reglas de asociación que
pueda realizar el cálculo en paralelo sobre un cluster Hadoop?
He visto los paquetes que 'paralelizan' R, pero no mencionan nada acerca de
modelos de reglas de asociación.
Saludos

Hadoop
Hola buenas,
me preguntaba si alguno usa hadoop Spark en su día día y si me podíais
recomendar un buen curso para empezar. Estuve en la charla de meetup de
madrid hace unos meses de Rspark y estuvo bien, ahora me preguntaba si es
posible profundizar.
Pero me gustaría tener recomendaciones de cualquier material que podáis
recomendar, cursos de coursera que hayais hecho, libros que hayais leido,

update_attributes updates data from second instance of nested form but not the first
Got a weird situation with an update put to a controller with a form with
nested attributes.
On the data below, I am updating data for both items (''0'' and ''1'') in
rosters_attributes (in the example below I am updating the ''name'' attribute
to a new value in both cases. What I am stuck on is that ''1'' gets its data

I''m using ROR 1.0 and script.aculo.us 1.5.1. I''ve been trying
unsuccessfully to render a partial in a DIV, but can''t seem to get the

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
