> SQL / Hive Context fails with NullPointerException while getting configuration from SQLConf.
This happens when the MemoryStore is filled with lot of broadcast and started dropping and
then SQL / Hive Context is created and broadcast. When using this Context to access a table
fails with below NullPointerException.
> Repro is attached - the Spark Example which fills the MemoryStore with broadcasts and
then creates and accesses a SQL Context.
