Hi, I've been trying to use HiveContext(instead of SQLContext) in my SparkSQL application and when I run the application simultaneously, it only works on the first call and every other call throws the following error-
ERROR Datastore.Schema: Failed initialising database.

changed HiveContext to SQLContext and everything worked fine. Can I make some configuration changes and run concurrent applications with HiveContext as well? Please suggest some solution. Thanks in advance.
