sparkr - JVM is not ready after 10 seconds -


i configured sparkr tutorials, , working. able read database read.df, nothing else works, , following error appears:

error in sparkr.init(master = "local") : jvm not ready after 10 seconds

why appear suddenly? i've read other users same problem, solutions given did not work. below code:

sys.setenv(spark_home= "c:/spark") sys.setenv(hadoop_home = "c:/hadoop") .libpaths(c(file.path(sys.getenv("spark_home"), "r", "lib"), .libpaths())) library(sparkr)  #initialeze sparkr environment sys.setenv('sparkr_submit_args'='"--packages" "com.databricks:spark-csv_2.11:1.2.0" "sparkr-shell"') sys.setenv(spark_mem="4g")  #create spark context , sql context sc <- sparkr.init(master = "local") sqlcontext <- sparkrsql.init(sc)

try few things below:

  1. check if c:/windows/system32/ there in path.

  2. check if spark-submit.cmd has proper execute permissions.

  3. if both above things true , if giving same error, delete spark directory , again create fresh 1 unzipping spark gzip file.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
