> In this JIRA we'll design two interfaces:
> * SparkSessionState
> * SparkSessionPoolManager
> and then once that is agreed upon we'll design two implementations:
> * SparkSessionStateImpl
> * SparkSessionPoolManagerImpl
> the form and function of these will be similar to the Tez equivalents. However, TezSessionState
provides some implementation which SparkClient already provides (refreshLocalResources*).
Let's keep SparkSessionState lightweight and not remove functionality from SparkClient. The
scope of this jira is just to create the shells and basic functionality. The implementations
in this jira should be able to:
> * Share a SparkSessionImpl across queries
> * Defining when a session can be re-used
> * Take ownership of SparkContext objects (Note we can only have a single SC until SPARK-2243
is resolved)
