    Okay, that should fix it.
    
    BTW, another curious thing with Hive on JDBC: Hive inserts are _very_ slow, since it's starting a MapReduce job for every insert... So you'd expect them to prioritize the batch feature? Nope. No support. Every... Single... Insert... Becomes... It's... Own... Job... I think the integration test job uses around 10-15 seconds per insert on my laptop (granted, with Hive running in the MapR sandbox on VirtualBox, but the VM overhead shouldn't really be noticable).
    
    I have a feeling that JDBC isn't really prioritized, so we might at some point see if there's another more low-level API to connect to Hive.
    
    On the other hand, querying is fast, so in that regard it's fine.
