class SQLConf extends Serializable with Logging

A class that enables the setting and getting of mutable config parameters/hints.

In the presence of a SQLContext, these can be set and queried by passing SET commands into Spark SQL's query functions (i.e. sql()). Otherwise, users of this class can modify the hints by programmatically calling the setters and getters of this class.

SQLConf is thread-safe (internally synchronized, so safe to be used in multiple threads).
