> In NetworkClient.leastLoadedNode, it invokes `isReady` to  check if an established connection exists for the given node. `isReady` checks whether metadata needs to be updated also which wants to make metadata request first priority. However, if the to-be-sent request is metadata request, then we do not have to check this otherwise the loop in `leastLoadedNode` will do a complete iteration until the final node is selected. That's not performance efficient for a large cluster.
