I have installed RHADOOP in Hortonwork VM. when I am running mapreduce code to verify it is throwing an error saying

I am using user as :rstudio (not root.but has access to sudoer)

Streaming Command Failed!

Can anybody help me understanding the issue.I am not getting much idea to solve thios issue.

Sys.setenv(HADOOP_HOME="/usr/hdp/2.2.0.0-2041/hadoop")

    Sys.setenv(HADOOP_CMD="/usr/bin/hadoop")
    Sys.setenv(HADOOP_STREAMING="/usr/hdp/2.2.0.0-2041/hadoop-mapreduce/hadoop-streaming.jar")
    library(rhdfs)
    hdfs.init()
    library(rmr2)
    ints = to.dfs(1:10)
    calc = mapreduce(input = ints, map = function(k, v) cbind(v, 2*v)

)

I am getting the error and below is the error in rhadoop

Error in mr(map = map, reduce = reduce, combine = combine, vectorized.reduce, : hadoop streaming failed with error code 1

4
stop("hadoop streaming failed with error code ", retval, "\n")
3
mr(map = map, reduce = reduce, combine = combine, vectorized.reduce, in.folder = if (is.list(input)) { lapply(input, to.dfs.path) } else to.dfs.path(input), out.folder = to.dfs.path(output), ...
2
mapreduce(input = input, output = output, input.format = "text", map = map)
1
wordcount(hdfs.data, hdfs.out)

Your code worked fine for me on changing the HADOOP_CMD and HADOOP_STREAMING to match my system configuration (I'm running hadoop 2.4.0 on Ubuntu 14.04).

My suggestion is that:

  • Ensure that functional instance of hadoop is running i.e., the command jps on your terminal should show below output:

enter image description here

  • Ensure that rJava library gets loaded while you are loading library(rhdfs).
  • Ensure that you are referring to the correct streaming jar file.

Below is the R code and the output:

Sys.setenv("HADOOP_CMD"="/usr/local/hadoop/bin/hadoop")
Sys.setenv("HADOOP_STREAMING"="/usr/local/hadoop/share/hadoop/tools/lib/hadoop-streaming-2.4.0.jar")

library(rhdfs)
# Loading required package: rJava
# HADOOP_CMD=/usr/local/hadoop/bin/hadoop
# Be sure to run hdfs.init()

hdfs.init()
library(rmr2)
ints = to.dfs(1:10)
calc = mapreduce(input = ints, map = function(k, v) cbind(v, 2*v))

Output:

Your current implmentation is using Rstudio. Can you try writing the code in .R and run using the hadoop jar $HADOOP_HOME/contrib/streaming/hadoop-streaming.jar -input file-in-hadoop -output hdfs_output_dir -file mapper_file -file reducer_file -mapper mapper.R -reducer reducer.R

By the way your exception PipeMapRed.waitOutputThreads(): can be caused only when there isn't proper input/output path specified. Please do check your paths.

This should work.
