之后调用tf_euler.sample_node()接口会出core

Start by reproducing the tf_euler.initialize_graph call with the shown remote ZooKeeper settings, then inspect client/client_manager.cc:33, client/query_proxy.cc:97 and :124, and common/zk_server_monitor.cc:256. Trace why both shards report empty weight metadata before calling tf_euler.sample_node(); done should include a clear diagnosis and prevent the subsequent core.
