There is a bug at this page in the examples
I have file it in the JIRA It's SPARK-12019.
I don't know how to change the page.
But I think an example that shows how to write options would be great.
Like
sc <- sparkR.init(master="yarn-client",appName= "SparkR", sparkHome =
"/home/spark",
I try to write a third party datasource plugin for spark.
It works perfect fine in scala, but in R because I need to pass the
options, which is a map[string,string] in scala, and nothing in R works, I
failed.
I tried use named list in R, it cannot get the value since I use get in my
plugin to get
I found the answer myself.
options should be added like:
read.df(sqlContext,path=NULL,source="***",option1="",option2="" )
