I'm learning readCsvFile (I discover if the file ends on "/n", you will return a null exception)
*if I try to read only 1 column *
val text4 = env.readCsvFile[String]("file:data.csv" ,includedFields = Array(1))
The error is: he type String has to be a tuple or pojo type. [null]
*If I put > 1 column; (*1º and 2º in this case*)*
val text4 = env.readCsvFile [(String,String)]("data.csv"
,fieldDelimiter = ","
,includedFields = Array(0,1))
Read all columns from, CSV (3 in my example)
a,b,c aa,bb,c
