错误
i was trying to run the “cross component lineage with Apache Atlas, across apache sqoop, storm and hive” using your Tutorial (VM), but I encountered some problems. When I used the command “ssh root@127.0.0.1 –p 2222”, I received the following message: “ssh: connect to host 127.0.0.1 port 2222: Connection refused”.
Could you please advise me on how to resolve this error message? I tried it in both Linux and Windows 7. I used Oracle VM VirtualBox Manager
解决方法：
If you are you using NAT in VirtualBox, please confirm that host port 2222 is being forwarded to 22 on the guest. You can run
nc -zv 127.0.0.1 2222
to confirm whether network-level connectivity is established.
