similar to: Unable to execute Java MapReduce (Hadoop) code from R using rJava

Hi, I have a MapReduce Java code, which I am calling from R using rJava. I have prepared the R package and tested that successfully. But when I deployed the package in a cluster and executed it, I am getting ClassNotFoundException. If I run the same job directly without integrating with R, it runs perfectly. Here is my R code: library(rJava) muMstSpark <- function(mesosMaster = NULL, input =

Corect me if this is not the right place to post this. I have a mdbdriver.jar (to access an MSAccess file) under Linux. I bought the license from http://www.csv-jdbc.com/ guys. The driver work fine when tested with DBVisualizer or another JDBC thing. The problem is that driver needs 3 other more jar files to work. Under R I have tried this and does not work: > library(RJDBC) Loading required

Buenos días, Tengo instalado un cluster en una máquina virtual y he instalado R y Rstudio (sobre Ubuntu server 14.04 64 bits ) . Desde consola puedo entrar en R y ejecutar un ejemplo con mapreduce sin problemas. Pero cuando lo intento hacer desde Rstudio obtengo este error: 16/02/16 10:37:00 ERROR streaming.StreamJob: Job not successful! Streaming Command Failed! Error in mr(map = map, reduce =

Is there a way to query a package to see what dynamic shared libraries are loaded with it? The reason I ask is because during development, I want to unload libraries so that they can be reloaded without restarting R. I want to make it automatic so that you can just pass in the name of the package, and it will unload all the relevant shared libraries. Typically, the name of the shared library is

Hi All. I have a setup in which: - applications deployed in weblogic log directly to weblogic; - components of weblogic (domain, admin server, managed servers) log to proper files (default logging). I would like to connect logging to syslog server. Is it possible? As I have read it is possible to log from applications with log4j if they send logs to weblogic server (on weblogic level

I am only reporting this because it is the current release branch and not devel. R-2.13 from svn revision 55957 builds fine, but fails make check. This happened with a fresh svn checkout 12 hours ago and it still happens as of now. Two days ago I could build R-2.13 and it passed make check on the same system, so I doubt it is a system problem. But just in case my system details are a fresh

I am trying to invoke an in house developed java program from R and am running into some confusing issues. I've written this function: DoNormalSkew <- function() { .jaddClassPath("U:/development/software/untilities/ELVeSkew/dist/ELVeSkew.jar") .jpackage("U:/development/software/utilities/ELVeS/dist/ELVeSkew.jar") .jcall("java/lang/System", "V",

I've several web servers that use log4j to generate the logs. The log file currently appended to is called filename. The older, non-current logs are called filename.yyyy-mm-dd-hh. Obviously, rotation takes place once every hour and it's done automatically by log4j. Old logs are never deleted by log4j, something else must delete them. I need to rsync all the filename* files from all

Hi everybody, I tried to analyze a custom Affymetrix 3'-biased Array. So I wanted to make a cdf package. (My CDF file size is 1.12Go).

Hello. I have successfully built R on windows scores of times, and have never come across this problem.

Hi. contrary to other environments, the attributes of a *package* environment are dropped (from the new environment) when attach():ing it to the search() path. This might or might not be surprising, but have some side effects if rearranging/attaching package environments. # Example - Regular environments env <- new.env() attr(env, "foo") <- "bar" print(env) ##

Dear R users, I have just upgraded R v1.5.0 to v1.6.1 for Windows but have trouble loading my library of R only functions (no C calls). After examining the "library" script this difference was found: (v1.5.0) which.lib.loc <- dirname(pkgpath) descfile <- system.file("DESCRIPTION", package = package, lib.loc = which.lib.loc) if

Currently library() and attach() fail to locate an existing '.conflicts.OK' in a package wit name space, unless it is exported. Since there should be little interest in exporting '.conflicts.OK' otherwise, one may argue that those methods should look for '.conflicts.OK' even if it is not exported. If so, a patch for library() is: >svn diff library.R Index: library.R

Hello All, Having some issue with local machine, I need to locate myself on Amazon for running R and Hadoop with Amazon instance.
