title: Convert spark rdd to pandas dataframe
body: <p>I have an rdd with 15 fields. To do some computation, I have to convert it to pandas dataframe.</p>
  
  <p>I tried with df.toPandas() function which did not work. I tried extracting every rdd and separate it with a space and putting it in a dataframe, that also did not work.</p>
