SQLConf

A trait 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 trait can modify the hints by programmatically calling the setters and getters of this trait.

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