I tried to download druid code to compile myself but ran into issues when cloning the repo:
git clone firstname.lastname@example.org:druid-io/druid.git
Cloning into ‘druid’…
Warning: Permanently added the RSA host key for IP address ‘220.127.116.11’ to the list of known hosts.
Permission denied (publickey).
fatal: Could not read from remote repository.
Is there something wrong with the server or the Druid Doc needs to be updated: http://druid.io/docs/latest/Build-from-source.html.
