> Hello all,
> Could someone help me with the manipulation of csv file data. I have 'semicolon' separated
csv data including doubles and strings. I want to calculate the maximum/average of a column.
When I read the file using sc.textFile(test.csv).map(_.split(";"), each field is read as string.
Could someone help me with the above manipulation and how to do that.
> Or may be if there is some way to take the transpose of the data and then manipulating
the rows in some way?
> Thank you in advance, I am struggling with this thing for quite sometime
> Regards,
> Vineet
