Hi, My target has special requirements during register allocation - there is both a need to handle register pairing and to never spill a flag result reg-class (which might happen at -O0 for no obvious reason). Since neither of these issues seems to be supported, I have tried to pre-allocate these registers in the preRA pass. This has resulted in "using undefined physical register"

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

Hi, Where can I find glusterfs-hadoop-0.20.2-0.1.x86_64.rpm?

I''m new to puppet. I''m trying to use some real case examples to better understand how Puppet works. Here''s my case: exec { "usermod -d /home/hadoop -s /bin/bash hadoop": unless => "test `grep ^hadoop /etc/passwd | awk -F: ''{print $6}''` == ''/home/hadoop''" } The idea is the usermod would only

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: ".............Our experiments run on cluster with 8 nodes in total, one is mds/namenode, the rest are

Hi, I have trying to run a simple MR program using rmr2 in a single node Hadoop cluster. Here is the environment for the setup Ubuntu 12.04 (32 bit) R (Ubuntu comes with 2.14.1, so updated to 3.0.2) Installed the latest rmr2 and rhdfs from here<https://github.com/RevolutionAnalytics/RHadoop/wiki/Downloads>and the corresponding dependencies Hadoop 1.2.1 Now I am trying to run a simple MR

Hi, all, i try to check the performance of Map/Reduce of Gluster File system. Mapper side speed is quite good and it is sometimes faster than hadoop's map job. But in the Reduce Side job is much slower than hadoop. i analyze the result and i found the primary reason of slow speed is bad performance in Merging stage. Would you have any suggestion for this issue FYI check the blog

Greetings, Our environment consists of about 600 Redhat Enterprise Linux 3, 4, 5, and soon 6 servers. We use cfengine 2 currently, but plan on migrating to puppet. Right now, we have our root-owned cfengine client running every 15 minutes from cron contacting a single cfservd server. Additionally, our employees start their own cfengine and puppet instances on on some servers running under

I have the following in vagrantfile in WIndows system. config.vm.provision :puppet do |puppet| puppet.manifests_path = "manifests" puppet.manifest_file = "base-hadoop.pp" puppet.module_path = "modules" end when i run vagrant provision, i do see manifest and module folders are mounted and ssh into vm, I can find files in the following path

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

I''m trying to automatically create users as a requirement for ssh keys to work. Here is my issue. I am getting this error from the agent. The SSH part works fine, but it will not create the user due to a dependency issue. I do not know how to debug this. err: Could not run Puppet configuration client: Could not find dependency Generic::Mkuser[hadoop] for Ssh::Authorized_keys[hadoop] at

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

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: http://www.teraproc.com/front-page-posts/r-on-demand/ Gracias, Carlos.

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)

Hi all, Has anyone created a Xen cluster to run a hadoop vm cluster? I would be interested in how it performs Thanks Lance -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

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

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,
