[fatma elsafoury]

Hi,

Hadoop streaming works fine with me when i try examples like wordcount but when i try to call R package 

of any type in the map function i get streaming error code 1. here is the code

Sys.setenv("HADOOP_CMD"="/usr/local/CELLAR/hadoop/2.7.1/bin/hadoop")

Sys.setenv("HADOOP_STREAMING"="/usr/local/Cellar/hadoop/2.7.1/libexec/share/hadoop/tools/lib/hadoop-streaming-2.7.1.jar")

Sys.setenv("HADOOP_HOME="="/usr/local/Cellar/hadoop/2.7.1")

# load librarys

library(rmr2)

library(rhdfs)

# load sample data

data(iris)

# init hdfs

hdfs.init()

# push data to hdfs

iris.dfs <- to.dfs(iris)

# define map function

iris.map <- function(k, v) {

   library(kernlab)

   lssvm(v$Species ~ ., data=v)

  String(x)

}

# rum mar job

iris.svm <- mapreduce(input=iris.dfs, map=iris.map)

Thank you

Please follow the debugging steps at: https://github.com/RevolutionAnalytics/RHadoop/wiki/user%3Ermr%3EDebugging-rmr-programs 

If you still run into issues, please include the stdio error logs, since most errors show up as "Error code 1" in the R console.
