JIRA is not a good place to ask questions -- please use user@spark.apache.org. This is for reporting issues, so I'd recommend closing this.

> 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
