fqaiser94 updated SPARK-32511:
------------------------------
Description:
Based on the discussions in the parent ticket (SPARK-22231), add a new
{{dropFields}} method to the {{Column}} class.
This method should allow users to drop a column nested inside a StructType
Column (with similar semantics to the existing {{drop}} method on {{Dataset}}).
It should also be able to handle deeply nested columns through the same API.
This is similar to the {{withField}} method that was recently added in
SPARK-31317 and likely we can re-use some of that "infrastructure."
The public-facing method signature should be something along the following
lines:
{noformat}
def dropFields(fieldNames: String*): Column
{noformat}
