      Description

      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

        // TODO: temporary interface. LLAP daemon should init this once during
        //       startup then others should use get w/o configuration.
