  • get(filename)
  • getrootdirectory()

Let us understand them in detail.


It specifies the path of the file that is added through SparkContext.addFile().


It specifies the path to the root directory, which contains the file that is added through the SparkContext.addFile().
from pyspark import SparkContext
from pyspark import SparkFiles
finddistance = "/home/hadoop/examples_pyspark/finddistance.R"
finddistancename = "finddistance.R"
sc = SparkContext("local", "SparkFile App")
print "Absolute Path -> %s" % SparkFiles.get(finddistancename)
