loadbalancer：c_murmurhash
当某个下游实例由于某些原因被SetFailed之后，后台会启动启动一个健康检查线程定时(间隔由参数-health_check_interval控制)检查被屏蔽的实例是否恢复正常。对于hash类型的loadbalancer，SelectServer(const
SelectIn& in, SelectOut* out)函数中的in.has_request_code必须是true，否则会输出错误日志并返回NULL;
`
if (!in.has_request_code) {
LOG(ERROR) << "Controller.set_request_code() is required";
return EINVAL;
`
如果下游实例只有几个，在某些情况下，有可能这些实例都被SetFailed了，从而导致后续的所有的请求都会失败。
