after long , difficult installation process of sparkr getting new problems of launching sparkr.

my settings

now try use following code in r:

library(devtools) library(sparkr) sys.setenv(spark_mem="1g") sys.setenv(spark_home="c:/spark-1.4.0") sc <- sparkr.init(master="local") 

i recieve following:

jvm not ready after 10 seconds 

i trying add system variables spark path or java path.

do have advices me fix problems.

the next step me after testing local host start tests on running hadoop cluster.

i think bug has been resolved. try following,

sys.setenv(spark_home="c:\\spark-1.4.0")  .libpaths(c(file.path(sys.getenv("spark_home"), "r", "lib"), .libpaths()))  library("sparkr", lib.loc="c:\\spark-1.4.0\\lib") # use of \\ windows environment.  library(sparkr)  sc=sparkr.init(master="local")
