scala - Spark error: "ERROR Utils: Exception while deleting Spark temp dir:" -


edit: adding details requested

while running simple spark code written in scala, locally on windows 7 64bit in administrator mode, execution ends in error detailed below. code write output expected (saveastextfile) before throwing error.

(based on google search, others have same problem adding sc.stop() @ end of code suggested on board not help.)

the code:

import org.apache.spark.sparkcontext import org.apache.spark.sparkconf  object test {     def main(args: array[string]) {          system.setproperty("hadoop.home.dir", "c:/prog/winutil/")            val inputfile1 = "./textinput.txt"           val conf = new sparkconf().setappname("testing")         val sc = new sparkcontext(conf)          val data = sc.textfile(inputfile1)                val outputfile = "./output"         data.saveastextfile(outputfile)          sc.stop()            } }

and error message:

fixed me after moving count() & take() statements on rdd before saving parquet using saveasparquetfile. try moving rdd.take() before u call saveasparquetfile.
