[bug] About nb10-sql-dataframes.ipynb (DF.map→RDD.map)

[Hiroyuki93]

@jadianes
hello I'm Hiroyuki.
nice Tutorial, Thank you!

In[7]

tcp_interactions_out = tcp_interactions.map(lambda p: "Duration: {}, Dest. bytes: {}".format(p.duration, p.dst_bytes))
for ti_out in tcp_interactions_out.collect():
  print ti_out

but map can use only for RDD.
so we need to change tcp_interactions(DataFrame) to RDD , I think.

here is the sample

tcp_interactions_out = tcp_interactions.rdd.map(lambda p: "Duration: {}, Dest. bytes: {}".format(p.duration, p.dst_bytes))
for ti_out in tcp_interactions_out.collect():
  print ti_out

how do you think about it?

If there is my mistake in my code or in my sentence , sorry. (couse Im not good at writting English)
please forgive me if I make you feel bad.
