HiveContext use derby as the metastore database defaultly which only
support single instance for one metastore path.
I think you need config the ```javax.jdo.option.ConnectionURL``` before
creating the HiveContext
you can change getorcreate like this:
```
def getOrCreate(sparkContext: SparkContext, config: Map[String, String] =
Map.empty): HiveContext = {
INSTANTIATION_LOCK.synchronized {
if (lastInstantiatedContext.get() == null) {
new HiveContext(sparkContext) {
override def configure(): Map[String, String] = config
}
}
}
lastInstantiatedContext.get()
}
```
then when you create hivecontext in HiveContextSuite, you can configure it
like this
```
val hiveContext = HiveContext.getOrCreate(testSparkContext,
HiveContext.newTemporaryConfiguration)
```
