cannot cast to double from spark row

[KhajaAsmath Mohammed]

Hi,

I am getting below error when trying to cast column value from spark
dataframe to double. any issues. I tried many solutions but none of them
worked.

 java.lang.ClassCastException: java.lang.String cannot be cast to
java.lang.Double

1. row.getAs[Double](Constants.Datapoint.Latitude)

2. row.getAs[String](Constants.Datapoint.Latitude).toDouble

I dont want to use row.getDouble(0) as position of column in file keeps on
change.

Thanks,
Asmath
