Hi Manorama, Think this continues from there onwards as well. I mean, even if we continued from the UI, at the model building step, you will notice that the model building is failing.
The issue was with the spark filter we used to remove the header. Reason behind this was, spark reads each row with quotes. But the header row we had stored from some earlier step ignores the quotes, and was stored as string. So when the header removal filter compares the header row we had stored, against each row read by spark, return is always false. Hence the actual header row does not get removed at any point. This eventually breaks the model building as there are multiple data types in a column (due to the header row). Not sure whether this was automatically fixed after the Dataset summary calculation was also done using Spark, rather than Apache commons CSV reader. Thanks for looking in to it.
