Can't add Windows workers due to a missing sh shell

Specific Domains Julia at Scale

I am trying to add workers on a Windows 10 node from a Windows 10 master.
Identical Julia 0.7.0 and passwordless login are set up correctly.

However addprocs( [(remote_ip,6)] ) fails with the error message:
‘sh’ is not recognized as an internal or external command

I would greatly appreciate any advice.

EDIT: Even if there is no solution, it would be a help to know this.

There is no immediate fix that I can think of. addprocs ends up calling https://github.com/JuliaLang/julia/blob/1f1b1b8c4e27668efddcaceb59db9422bb274cfd/stdlib/Distributed/src/managers.jl#L148 which assumes a Unix environment with sh being available. I don’t know if anyone ever tried this with Windows 10.

Can you ssh to that machine? What shell does that drop you in?

Thank you very much for your answer.

I can ssh from Windows 10 to Windows 10 without a password,
arriving at the the default cmd.exe prompt.

Sounds like an untrodden path.
Should I give it up for now?

Is it cmd or powershell? If you are strongly interested in this you could probably implement your own ClusterManager for WindowsSSH and/or contribute to the existing one to fix the Unix only assumptions.

It is the plain cmd.exe, not powershell.

Thank you very much for creating an issue for this,
but unfortunately I am not qualified to solve it.
