> 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.

> Fix is to remove broadcasting SQL/Hive Context or Increasing the Driver memory.
