Spark 2.0, DataFrame, filter a string column, unequal operator (!==) is deprecated

Question

I am trying to filter a DataFrame by keeping only those rows that have a certain string column non-empty.

The operation is the following:

df.filter($"stringColumn" !== "") 

My compiler shows that the !== is deprecated since I moved to Spark 2.0.1

How can I check if a string column value is empty in Spark > 2.0?

Answer 1

Use =!= as a replacement:

df.filter($"stringColumn" =!= "")
