Question

After long and difficult installation process of SparkR i getting into new problems of launching SparkR.

My Settings

R 3.2.0

Answer 1

I also had this error, from a different cause. Under the hood, Spark calls

system2(sparkSubmitBin, combinedArgs, wait = F)

There are many ways this can go wrong. In my case the underlying error (invisible until calling system2 directly as an experiment) was ""UNC path are not supported." I had to change my working directory in R studio to a directory which was not part of a network share, and then it started working.
