How to add DataNode to Cloudera hadoop

Question

I am trying to add a Datanode to my existing Single Datanode. Since my Unix server does not have access to Internet , Cloudera Manager is unable to perform the installation as it throws below error. Is there any other CLI Method to Add Data Node instead of CM?

Yes, there are two approaches (I'm keeping this Cloudera-specific since this is what you mentioned).

1) Download tarballs and install everything manually. There is a guide available here , and I think it is not a good candidate to be copied here on Stack Overflow, because it is very long and vendor-specific (if the document moves, the title is "Installation Path C - Installation Using Tarballs").

2) For large internal installations, you may consider setting up your own repositories with rpm packages that you can access with yum. For this you'll need to edit /etc/yum.repos.d and link to some accessible host that's going to be your repo server (of course, you'll have to put your files there in advance). More details here . You can download rpms here . I have never had to do this myself, so I help this will point you in the right direction.
