             Summary: SparkSession.conf fails when given default value with Python 3
                 Key: SPARK-25397
                 URL: https://issues.apache.org/jira/browse/SPARK-25397
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 2.3.1
            Reporter: Joseph K. Bradley


Spark 2.3.1 has a Python 3 incompatibility when requesting a Conf value from SparkSession when you give non-string default values.  Reproduce via SparkSession call:
{{spark.conf.get("myConf", False)}}

This gives the error:
{code}
>>> spark.conf.get("myConf", False)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/josephkb/work/spark-bin/spark-2.3.1-bin-hadoop2.7/python/pyspark/sql/conf.py", line 51, in get
    self._checkType(default, "default")
  File "/Users/josephkb/work/spark-bin/spark-2.3.1-bin-hadoop2.7/python/pyspark/sql/conf.py", line 62, in _checkType
    if not isinstance(obj, str) and not isinstance(obj, unicode):
*NameError: name 'unicode' is not defined*
{code}

The offending line in Spark in branch-2.3 is: https://github.com/apache/spark/blob/branch-2.3/python/pyspark/sql/conf.py which uses the value {{unicode}} which is not available in Python 3.
