Add support for shipping SparkR package for R workers required by RDD APIs.
Tested createDataFrame() by creating a DataFrame from an R list.
Remove sparkRLibDir parameter of sparkR.init(). Determine SparkR package
location on each worker node according to the deployment mode (this allows
node-specific SPARK_HOME). Not sure if there is better solution. A rough code
scan about pySpark does not tell me how pySpark locates pySpark.zip in various
deployment modes. @davies , could you help to give me a hint and review this
patch?
Next, I'd like to refactor this code to align with SPARK-5479 (moves YARN
specific code from SparkSubmit to deploy/yarn) @shivaram, do you think I
refactor code in this patch or do it in a new JIRA?
