    The errors in the log file don't seem to be related to the changes I made? They are primarily
in PythonRDD.scala:
    java.net.SocketException: Socket is closed
    
    org.apache.spark.SparkException: Python worker exited unexpectedly (crashed)
    	at org.apache.spark.api.python.PythonRunner$$anon$1.read(PythonRDD.scala:203)
    	at org.apache.spark.api.python.PythonRunner$$anon$1.<init>(PythonRDD.scala:207)
    	at org.apache.spark.api.python.PythonRunner.compute(PythonRDD.scala:125)
    	at org.apache.spark.api.python.PythonRDD.compute(PythonRDD.scala:70)
    
    Caused by: java.io.EOFException
    	at java.io.DataInputStream.readInt(DataInputStream.java:392)
    	at org.apache.spark.api.python.PythonRunner$$anon$1.read(PythonRDD.scala:139)
    
    Errors seem to be from PythonRDD.scala, but I made no changes to that file, and I'm not
sure how changing R code affects that interface?
    
    Can someone else take a look? @shivaram, @sun-rui
