Hi, Du I am not sure what you mean "triggers the HiveContext to create a database", do you create the sub class of HiveContext? Just be sure you call the "HiveContext.sessionState" eagerly, since it will set the proper "hiveconf" into the SessionState, otherwise the HiveDriver will always get the null value when retrieving HiveConf.

I have an akka Actor that processes database requests in high-level messages. Inside this Actor, it creates a HiveContext object that does the actual db work. The main thread creates the needed SparkContext and passes in to the Actor to create the HiveContext. When a message is sent to the Actor, it is processed properly except that, when the message triggers the HiveContext to create a database, it throws a NullPointerException in hive.ql.Driver.java which suggests that its conf variable is not initialized. Ironically, it works fine if my main thread directly calls actor.hiveContext to create the database. The spark version is 1.1.0. Thanks, Du
