Error on Cluster Node Add

So, was able to get the node to add by trying another node's address that was already in the cluster. It worked, but still curious as to why I was getting that error when trying to add to the 1st node.
Just a shot in the dark, from the error message seems that you don't have 'mkdir' command available in the server (don't know which one). Check if is the case (i.e. issue the command 'which mkdir'). If is absent, install the package "coreutils", but is really strange and scaring if it's missing...
 
Also, when logging into ssh, i'm getting this in the console:
Code:
-bash: id: command not found
-bash: [: : integer expression expected
I am starting to get the feeling that there is something that was unintentionally changed with one of the profile settings.
