-----------------------------------
Summary: SQLContext.getConf(key, null) should return null, but it
throws NPE
Key: SPARK-21588
URL: https://issues.apache.org/jira/browse/SPARK-21588
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 2.2.0
Reporter: Burak Yavuz
Priority: Minor
SQLContext.get(key) for a key that is not defined in the conf, and doesn't have
a default value defined, throws a NoSuchElementException. In order to avoid
that, I used a null as the default value, which threw a NPE instead. If it is
null, it shouldn't try to parse the default value in `getConfString`
