Apache storm streamparse向本地主机提交问题

当我尝试向集群提交streamparse拓扑时（这里我使用localhost作为streamparse的conf.json文件中的nimbus和worker），我得到了这个错误

(homeenv)nandaraj@nandaraj-ThinkCentre-Edge72:~/streamparse/wordcount$ sparse submit -n wordcount -e prod
[localhost] Executing task '_create_or_update_virtualenv'

Fatal error: Needed to prompt for a connection or sudo password (host: localhost), but input would be ambiguous in parallel mode

Aborting.

我遇到了和你一样的问题，我自己解决了。

可能您在config.json中配置的“用户”是“storm”或其他不在主机中的内容，因此更改为“root”。

默认情况下，streamparse使用ssh进行通信，因此您需要在配置中提供用户和密码

您可以执行以下操作来解决此问题。 请检查config.json

{
    "serializer": "json",
    "topology_specs": "topologies/",
    "virtualenv_specs": "virtualenvs/",

    "envs": {
        "prod": {

            "user": "testuser",
            "ssh_password": "password",
            "nimbus": "localhost",
            "workers": ["localhost"],
            "log": {
                "path": "/var/log",
                "max_bytes": 1000000,
                "backup_count": 10,
                "level": "info"
            },
            "virtualenv_root": "/work/virtualenv"
        }
    }
}

“用户”和“ssh_密码”必须在操作系统中有效。 就我而言，我一直在乌班图这样做。 您可以像这样检查ssh服务

sudo service ssh status

如果ssh服务未启动，则必须首先启动它

sudo apt-get install openssh-server
sudo service ssh start
