我在做一个 streamparse 在安装了zookeeper和nimbus的aws示例上进行项目。我想使用storm ui。我跑了 sparse submit 使用以下config.json文件：

{
    "library": "",
    "topology_specs": "topologies/",
    "virtualenv_specs": "virtualenvs/" ,
    "envs": {
        "prod": {
            "user": "ubuntu",
            "nimbus": "127.0.0.1",
            "workers": [
                "127.0.0.1"
            ],
            "log": {
                "path": "/var/log/storm/streamparse",
                "max_bytes": 100000,
                "backup_count": 10,
                "level": "info"
            },
            "use_ssh_for_nimbus": false,
            "use_virtualenv": false,
            "virtualenv_root": ".virtualenvs/storm"
        }
    }
}

它给出了以下错误跟踪：
