Shivaram Venkataraman commented on SPARK-8603:
----------------------------------------------
So a few points about the steps
1. If you download a pre-built version you don't need to recompile Spark i.e.
you don't need to run mvn install etc. Also just curious: What tool did you use
to unzip the tar.gz file on Windows ?
2. You don't need to start the spark master, spark worker to try out Spark on a
single machine -- You can just set the master to "local" and that doesn't need
separate binaries for Master, Worker.
3. I have seen a similar problem before, but not because of the file separator
but because the spark-submit.cmd file was not marked as executable. This
happened because unzipping a tar.gz didn't set permissions correctly (This
relates to point (1)).

> In windows ,creation of spark context fails using below code from R studio
> Sys.setenv(SPARK_HOME="C:\\spark\\spark-1.4.0")
> .libPaths(c(file.path(Sys.getenv("SPARK_HOME"), "R", "lib"), .libPaths()))
> library(SparkR)
> sc <- sparkR.init(master="spark://localhost:7077", appName="SparkR")
> Error: JVM is not ready after 10 seconds
> Reason: Wrong file path computed in client.R. File seperator for windows["\"]
