HDP Sandbox comes pre-installed with SparkR and R .

First let's setup the R Studio on the HDP Sandbox:

To download and install RStudio Server open a terminal window and execute the commands corresponding to get the 64-bit version

wget https://download2.rstudio.org/rstudio-server-rhel-0.99.893-x86_64.rpm

sudo yum install --nogpgcheck rstudio-server-rhel-0.99.893-x86_64.rpm

sudo rstudio-server verify-installation

sudo rstudio-server stop

sudo rstudio-server start

Now setup a local user on the hdp sandbox, to access the rstudio:

useradd alex

passwd xxxx

Next launch web-browser and point to : http://sandbox.hortonworks.com:8787/

Login using the local account created earlier above.

Next lets initialize the sparkr in "yarn-client" mode

Sys.setenv(SPARK_HOME="/usr/hdp/current/spark-client/")


.libPaths(c(file.path(Sys.getenv("SPARK_HOME"),"R","lib"),.libPaths()))


library(SparkR)


sc <- SparkR::sparkR.init(master = "yarn-client") 

Run the code in rstudio , you should get the following output:

> 
> 
> Sys.setenv(SPARK_HOME="/usr/hdp/current/spark-client/")
> 
> .libPaths(c(file.path(Sys.getenv("SPARK_HOME"),"R","lib"),.libPaths()))
> 
> library(SparkR)

Attaching package: ‘SparkR’

The following objects are masked from ‘package:stats’:

    cov, filter, lag, na.omit, predict, sd, var

The following objects are masked from ‘package:base’:

    colnames, colnames<-, intersect, rank, rbind, sample, subset, summary, table, transform

> sc <- SparkR::sparkR.init(master = "yarn-client")

Validate that the sparkUI is started, look for this message in your output like the one above:

16/04/01 16:28:03 INFO Utils: Successfully started service 'SparkUI' on port 4040.
16/04/01 16:28:03 INFO SparkUI: Started SparkUI at http://192.168.197.154:4040

Next lets try running some sparkR code:

sqlContext <-sparkRSQL.init(sc)

path <-file.path("file:///usr/hdp/2.4.0.0-169/spark/examples/src/main/resources/people.json")

peopleDF <-jsonFile(sqlContext, path)

printSchema(peopleDF)
You should get this output:
> printSchema(peopleDF)
root
 |-- age: long (nullable = true)
 |-- name: string (nullable = true)

Now lets try to do some basic dataframe analysis 
# Register this DataFrame as a table.
registerTempTable(peopleDF, "people")
teenagers <- sql(sqlContext, "SELECT name FROM people WHERE age >= 13 AND age <= 19")
teenagersLocalDF <- collect(teenagers)
print(teenagersLocalDF)

Hi @azeltov,

Could you run R-Studio remote, i.e. on your laptop and connect to a cluster?

Cheers,

I installed HDP2.4 for Virtual box and it is telling me that R is not found. Are you sure that R is preinstalled? What is the fix for this?

New Contributor

This did not work. When I verify my installation it gives me: Unable to find an installation of R on the system (which R didn't return valid output); Unable to locate R binary by scanning standard locations.

What to do?

It seems the new version of Sandbox does not have R pre-installed. Its an easy installation procedure :

sudo yum install -y epel-release 
sudo yum update -y 
sudo yum install -y R

HI @azeltov, I am trying to install R-studio on Hortonworks sandbox 2.5, running through the exception in verify installation step:

initctl: Unable to connect to Upstart: Failed to connect to socket /com/ubuntu/upstart: Connection refused

I have tried starting, stopping rstudio server, it shows the same message.

PS: Since it is a docker container, 8787 port is not opened so I have configured /etc/rstudio/rserver.conf to use port 9000.
