* removing ‘/usr/lib64/R/library/rhdfs’

I have tried doing many round of iterations, still no go. Iam unable to install rhdfs and rmr2. I have already set HADOOP_CMD, JAVA_HOME, PATH AND installed rjava in R evironment in cludera. Iam unable to load rhdfs at all. Please help with this, or should I uninstall everything from R - R, Studio and reinstall again. Please help..

When I try installing rhdfs in R it gives me this error:

> install.packages("rhdfs")
Installing package into ‘/home/supstat/R/x86_64-unknown-linux-gnu-library/2.13’
(as ‘lib’ is unspecified)
Warning in install.packages :
  package ‘rhdfs’ is not available (for R version 3.1.0)

Solution

I faced several issues while trying to install RHadoop, and all of them had to do with rjava. Export the HADOOP_CMD and HADOOP_STREAMING variables. After that, you need to tell R library path to point to where your Java installation is:

export LD_LIBRARY_PATH=/usr/lib/jvm/java-7-oracle/jre/lib/amd64/server

Then, you need to run the following command:

R CMD javareconf -e

After that you should be able to install rhdfs and rmr2. If I remember correctly you need to install rmr2 before installing rhdfs, or maybe it was the other way around.

EDIT: try to configure it and install from inside R:

Sys.setenv(HADOOP_CMD="the same value you used outside R")
Sys.setenv(HADOOP_STREAMING="same as above")
install.packages("rhdfs_1.0.8.tar.gz", repos=NULL, type="source")
