Michael Armbrust commented on SPARK-9776:
-----------------------------------------
You can only have one hive context running when you are using derby for the
metastore (the default). {{bin/spark-shell}} automatically creates a
HiveContext on startup (it checks the classpath and creates a HiveContext if
possible, otherwise falls back on creating a SQLContext). So the one you are
creating by hand will always fail since the database is locked.
> Another instance of Derby may have already booted the database
