Reynold Xin updated SPARK-17338:
--------------------------------
Description:
Global temporary view is a cross-session temporary view, which means it's
shared among all sessions. Its lifetime is the lifetime of the Spark
application, i.e. it will be automatically dropped when the application
terminates. It's tied to a system preserved database global_temp(configurable
via SparkConf), and we must use the qualified name to refer a global temp view,
e.g. SELECT * FROM global_temp.view1.
> Add global temp view support
