I have a rather odd use case. I have a DataFrame column name with a + value
in it.
The app performs some processing steps before determining the column name,
and it
would be much easier to code if I could use the DataFrame filter operations
with a String.
This demonstrates the issue I am having:
dataFrame.filter(renamed("A+B").equalTo(2.0)).show()
This will return all rows with the column value matching 2.0, as expected.
dataFrame.filter("\"A+B\"=2.0").show()
This executes but does not return the correct results. It returns an empty
result.
dataFrame.filter("\"A+C\"=2.0").show()
Referencing a non-existent column name returns the same empty result.
Any suggestions?
