Error while running MR using rmr2
...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 program as
Sys.setenv(HADOOP_HOME="/home/training/Installations/hadoop-1.2.1")
Sys.setenv(HADOOP_CMD="/home/training/Installations/hadoop-1.2.1/bin/hadoop")
library(rmr2)
library(rhdfs)
ints = to.dfs(1:100)
calc = mapreduce(input = ints, map = function(k, v) cbind(v, 2*v))
from.dfs(calc)
The mapreduce job fails with the below error message in *
hadoop-1.2.1/logs/userlogs/job_201310091...
