Hi,

Suppose your data frame is in "data" variable and you want to print it.

Its simple and one line function to print the data of dataframe in scala.

Here is sample code:

data.collect.foreach(println)

First of all you have to call the collect function to get all data distributed over cluster.

Then you can call foreach() function and use println() function the print the data.

Thanks
