Did you follow these steps http://hortonworks.com/hadoop-tutorial/apache-spark-1-6-technical-preview-with-hdp-2-3/

SparkR is new to HDP and this is the first preview where it is offered

I only see spark 1.4.1 libraries in your directory listing, sparkr is in 1.6.0 you need to point your environment to the proper release

Re: sparkR doesnt work HDP

@Roberto Sancho You have to follow the tutorial step by step to make it work http://hortonworks.com/hadoop-tutorial/apache-spark-1-6-technical-preview-with-hdp-2-3

Also, you can follow https://gist.github.com/nsabharwal/9163e0adfc66af080145 but I suggest to stick with the tutorial

Please see the output that I posted. In your case, there is no R package with in spark
