             Summary: No exception using DataFrame.withColumnRenamed when existing column doesn't exist
                 Key: SPARK-16651
                 URL: https://issues.apache.org/jira/browse/SPARK-16651
             Project: Spark
          Issue Type: Bug
          Components: PySpark
    Affects Versions: 1.5.0
            Reporter: Tom Phillips


The {{withColumnRenamed}} method does not raise an exception when the existing column does not exist in the dataframe.

Example:

{code}
In [4]: df.show()
+---+-----+
|age| name|
+---+-----+
|  1|Alice|
+---+-----+


In [5]: df = df.withColumnRenamed('dob', 'date_of_birth')

In [6]: df.show()
+---+-----+
|age| name|
+---+-----+
|  1|Alice|
+---+-----+
{code}
