I also had this issue. When you try to trace it, you'll find out that
when you manually connect to a machine and immediately execute a
command, it will inherit your environment, not the environment of the
$ ssh node1 && echo $PATH
This will echo the PATH on your computer, the master one, not the node.
But if you do this:
$ ssh node1
node1$ echo $PATH
it will echo the PATH on your node.
Solution to this is to write the path to the executables and path to
libraries to the variables you have set on your own computer, tha
Let me know how that works for you!
