> Right now LLAP IO is a singleton that is initialized on first use with configuration of the caller (first query).
> It needs to be initialized once before queries are accepted instead... see LlapIoProxy.java
> {noformat}
>   // TODO: temporary interface. LLAP daemon should init this once during
>   //       startup then others should use get w/o configuration.
