java - Spark: rdd.collect() runs fine but rdd.take(5) throws an exception -

i relatively new spark. installed spark in standalone mode on windows. when try use rdd.take(5), throws following exception:

py4jjavaerror: error occurred while calling z:org.apache.spark.api.python.pythonrdd.runjob. : org.apache.spark.sparkexception: job aborted due stage failure: task 0 in stage 4.0 failed 1 times, recent failure: lost task 0.0 in stage 4.0 (tid 7, localhost): java.net.socketexception: connection reset peer: socket write error

eventhough, rdd.collect() runs successfully, rdd.take() throws error. can reason happening?

edit: adding code:

import findspark findspark.init("c:\users\polestaremployee\spark-1.6.3-bin-hadoop2.6") pyspark import sparkcontext, sparkconf sc = sparkcontext() data = sc.textfile("train.csv") data.take(20) 

edit2: first rows of data this: (pasting partial part of result got using collect())
