dataframe writeCSV adds blank line

[lynnjo]

Whenever I output a csv, a blank line is always written at the top of the file. This happens whether I"m creating a dataframe from a list of objects, or if I read a csv file into a dataFrame, process it in some manner, and then write it back out. I always get a blank line as the first line. Is this intentional? How to prevent?

I am running a gradle project, using dataframe:0.8.0-dev-952
I have also seen this with the rc-7 load.

Easiest way to reproduce:

1. Read any comma-separated file into a dataframe,
2. Write the dataframe out to another file

val inputFile =
val myDF = DataFrame.readCSV(inputFile)

val outputFile =
myDf.writeCSV(outputFile

Hi! Thank you for the report. I don't think it's intentional, most likely it's a bug, I'll look into it tomorrow. For now, i can suggest using df.toCsv to get String, then remove leading characters and write it to a file.
